Homework Statement
The following three step mechanism has been proposed for the reaction of chlorine and chloroform
(1) [tex]Cl_2 (g) \rightleftharpoons 2Cl(g)[/tex]
(2) [tex]Cl (g) + CHCl_3 (g) \rightarrow HCl (g) + CCl_3 (g)[/tex]
(3) [tex]CCl_3 (g) + Cl(g) \rightarrow CCl_4[/tex]
The numerical values of the rate constants are for these steps are [tex]k_1 = 4.8 x 10^3[/tex], [tex]k_{-1} = 3.6 x 10^3[/tex], [tex]k_2 = 1.3 x 10^-^2[/tex], [tex]k_3 = 2.7 x 10^2[/tex] respectively.
Derive the magnitude of k for the overall reaction
2. Irrelevant Information
I spent two days on this problem (with another problem which I am about to post) and I am about to give up, it is due tonight and I just want to get over this and start studying my other midterm tomorrow
The Attempt at a Solution
So I wrote down the rate laws for each reaction
(1) Rate = k1[Cl2] = k-1[Cl]
(2) Rate = k2[Cl][CHCl3]
(3) Rate = k3[CCl3][Cl]
CL, CCl3 are intermediates so I got rid of them(1) Rate = k1[Cl2]
(2) Rate = k2[CHCl3]
(3) Rate = k3[CCl3]
