12.3 Exercise 14

Avg difficulty 2.5

Nitrogen monoxide reacts with chlorine according to the equation:
2NO(g)+Cl2(g)⟶2NOCl(g)\text{2NO}( g \left.\right) + \text{Cl}_{2} \left(g\right) \rightarrow \text{2NOCl}( g \left.\right)

The following initial rates of reaction have been observed for certain reactant concentrations:

[NO] (mol/L) [Cl2] (mol/L) Rate (mol L−1 h−1)
0.50 0.50 1.14
1.00 0.50 4.56
1.00 1.00 9.12

What is the rate law that describes the rate’s dependence on the concentrations of NO and Cl2? What is the rate constant? What are the orders with respect to each reactant?
