2. Why is concentration vs reaction rate linear for first order reaction ?
The reason why on order 1 reaction the concentration and reaction rate is linear for first order reaction, That's because experiments have shown that the rate of a reaction is directly proportional to the concentration.
Pembahasan
Reaksi primer adalah reaksi yang laju reaksinya sebanding dengan konsentrasi reaktannya. Dengan kata lain, menggandakan konsentrasi menggandakan laju reaksi. Reaksi primer dapat memiliki satu atau dua reaktan, seperti dalam kasus reaksi dekomposisi. Reaksi primer dapat didefinisikan sebagai reaksi kimia di mana laju reaksi bergantung secara linier pada konsentrasi hanya satu reaktan. Dengan kata lain, reaksi primer adalah reaksi kimia yang lajunya berubah berdasarkan perubahan konsentrasi hanya satu reaktan. Jadi orde reaksinya adalah 1.

16. 2. The following data were collected for the reaction2NO + Cl2 -------> 2 NOClExp NO (M) Cl2(M) Rates (M/s)1 0,01 0,01 0,0062 0,01 0,02 0,0123 0,02 0,01 0,0244 0,03 0,05 ?a. Write the expression for the rate law. b. Calculate the value of rate constant
Jika suatu reaksi kimia berlangsung berdasarkan persamaan berikut :
2NO + Cl2 ⇒ 2NOCl
dan diperoleh data sebagai berikut :
NO (M) Cl2 (M) v (M/s)
0.01 0.01 0.006
0.01 0.02 0.0.12
0.02 0.01 0.024
Berasarkan data tersebut diperoleh persamaan laju reaksi :
v = k [NO]ᵃ[Cl2]ᵇ
exp 1 ⇒ 0.006 = k [0.01]ᵃ[0.01]ᵇ
exp 2⇒ 0.012 = k [0.01]ᵃ[0.02]ᵇ
exp 3⇒ 0.024 = k [0.02]ᵃ[0.01]ᵇ
dari pers (1) dan (2) diperoleh :
0.012/0.006 = [0.02/0.01]ᵇ
2 = [2]ᵇ
maka b = 1
dari pers (2) dan (3) diperoleh :
0.024/0.012 = [0.02/0.01]ᵃ[0.01/0.02]
2 = [2]ᵃ[1/2]
4 = [2]ᵃ
a = 2
maka persamaan laju reaksi dapat dituliskan dengan :
v = k [NO]²[Cl2]
berdasarkan persamaan (1) maka diperoleh nilai tetapan laju reaksi k adalah
v = k [NO]²[Cl2]
0.006 = k [0.01]²[0.01]
0.006 = 0.000001 k
k = 6000
PembahasanLaju reaksi merupakan laju pengurangan konsentrasi zat pereaktan per satuan waktu dalam suatu reaksi kimia. Dalam suatu reaksi, konsentrasi zat pereaktan akan berkurang, sedangkan konsentrasi produk akan bertambah. Reaksi akan berlangsung hingga tidak terjadi perubahan konsentrasi lagi. Pada kondisi tersebut reaksi dikatakan mencapai kesetimbangan.
Prinsip laju reaksi didasarkan pada teori tumbukan. Reaksi tumbukan menyatakan bahwa partikel-partikel reaktan bergerak bebas secara acak, partikel-partikel bertumbukan sehingga terjadi reaksi. Tumbukn efektif merupakan tumbukan antar partikel yang menghasilkan reaksi kimia. Jika suatu reaksi kimia dinyatakan dengan :
aA + B ⇒ cC
Maka laju reaksi di rumuskan dengan :
v = k [A]ᵃ[B]ᵇ
dimana k adalah konstanta laju reaksi, [A] dan [B] adalah konsentrasi reakan dan a dan b ditentukan berdasarkan percobaan.
Laju reaksi bergantung pada beberapa faktor diantaranya :
Konsentrasi reaktan, reaktan denga konsentrasi pekat akan bereaksi lebih cepat, sehingga laju reaksi meningkat.temperatur, partikel-partikel memiliki cukup energi untuk bergerak akibat adanya temperatur. sehingga semakin tinggi temperatur jumlah tumbukan energi lebih banyak. Hal ini mengakibatkan peningkatan laju reaksi.Bentuk fisik reaktan, reaktan erbentuk serbuk halus akan lebih cepat bereaksi dibandingan yang berbentuk bongkahan arena memiliki luas permukaan aktif lebih besarkatalis merupakan zat yang mampu membercepat reaksi. keberadaan katalis tidak menjadi kontaminasi pada produk.Pelajari lebih lanjutkonstanta laju reaksi di link brainly.co.id/tugas/16342075Orde reaksi di link brainly.co.id/tugas/13003076Kesetimbangan reaksi di link brainly.co.id/tugas/13433982Detail tambahanKelas : XI SMA

B: Just give me a trim. I want to get my hair shorter. (Potong biasa saja. Saya mau buat rambut saya lebih pendek)
A: Would you like a razor cut or should I use the clippers? (Anda mau menggunakan pisau cukur atau saya pakai gunting saja?)
B: A razor cut for both sides, and use the clippers for the rest. (Pisau cukur untuk dua sisi samping, dan gunakan gunting untuk sisanya)
A: How about I give you more trim on these parts? It may look a bit like this picture. (Bagaimana jika saya potong lebih banyak di bagian-bagian sini? Mungkin akan jadi seperti gambar ini)
B: You mean, number 5? No, thanks. I don’t want to have a crew cut. (Maksud Anda, nomer 5? Tidak, terima kasih. Saya tidak mau potongan rambut cepak)
A: Alright, then. Sit up straight. (Baiklah kalau begitu. Duduk tegak)
Dialogue II
A: How are you doing? (Apa kabar?)
B: I’m good. I would like a cut and a shave, please. (Saya baik. Saya mau potong dan cukur, ya)
A: How would you like your hair this time? (Anda mau rambut Anda seperti apa kali ini?)
B: Trim around the ears, then take a little off the back. (Potong di bagian sekitar telinga, lalu ambil sedikit saja untuk bagian belakang)
A: You want to just leave the top like that? (Bagian atasnya tetap begitu saja?)
B: Yes. (Ya)
A: Should I shave your beard clean? (Haruskah saya cukur janggut Anda sampai bersih?)
B: Let this part remain still. (Sisakan bagian sini)
A: Do you want me to wash your hair first? (Mau saya cuci dulu rambutnya?)
B: No, thanks. I don’t have much time. (Tidak, terima kasih. Saya tidak punya banyak waktu)
Dialogue III
A: Come sit here. How shall I cut your hair, young man? (Silahkan duduk sini. Mau potong rambut model apa, anak muda?)
B: Just chop it all off and shave. I want to get a clean look. (Potong pendek semua dan cukur. Saya mau punya tampilan bersih)
A: Like, a very short cut and clean shave? (Jadi, potongan super pendek dan cukur bersih?)
B: Yes. Like this one, about an inch long. (Ya, seperti ini, panjang sekitar satu inchi)
A: Oh, number 8? Sure. Would you like it washed? (Oh, nomor 8? Baik. Mau dicuci dulu rambutnya?)
B: No, thank you. (Tidak, terima kasih)
A: Since your hair is kind of curvy, I guess we’ll need to get it straightened before I use the razor to get a better cut. Are you okay with that? (Sebab rambutmu agak bergelombang, kurasa kita harus meluruskannya dulu sebelum saya gunakan pisau cukur untuk potongan yang lebih baik. Tidak apa?)
B: Fine. Will it grow straight later? (Baiklah. Apakah akan tumbuh lurus nantinya?)
A: After your hair gets to this length, it will come curvy again. (Setelah rambutmu sepanjang ini, akan kembali bergelombang lagi)
B: Okay. Why don’t you get some new magazines, though? (Baiklah. Kenapa Anda tidak beli majalah baru?)
A: Most of my customers always get on their phone to kill the time so I didn’t think new magazines would be necessary. (Kebanyakan pelangganku selalu bermain ponsel untuk menghabiskan waktu, jadi kurasa tidak perlu majalah baru)
B: I see. (Aku mengerti)
