Chapter 12, Problem 33E

The decomposition of nitrosyl chloride was studied:

2NOCl(g) ⇌ 2NO(g) + Cl₂(g)

The following data were obtained where

$\text{Rate}=-\frac{\text{Δ}\left[\text{NOCl}\right]}{\Delta t}$

[NOCl]0(molecules/cm3)	Initial Rate (molecules/cm3 · s)
3.0 × 1016	5.98 × 104
2.0 × 1016	2.66 × 104
1.0 × 1016	6.64 × 103
4.0 × 1016	1.06 × 105

a. What is the rate law?

b. Calculate the value of the rate constant.

c. Calculate the value of the rate constant when concentrations are given in moles per liter.
