Expert Solution
Step 1

Given,

ClCH2CH2Cl (g) ➝ CH2CHCl (g) + HCl (g)

Rate law expression at certain temperature:

rate = (1.70 M-1. s-1) [ClCH2CH2Cl]2

From the above rate law expression we can say that reaction is a second order.

Rate constant (k) = 1.70 M-1. s-1

Initial concentration of ClCH2CH2Cl, [ClCH2CH2Cl]O = 1.43 M

Concentration of ClCH2CH2Cl after 3.70 s, [ClCH2CH2Cl] = ?

Time (t) = 3.70 s
