Chapter 11.5, Problem 11.9E

The frequency factor A is 6.31 × 10⁸ L mol⁻¹ s⁻¹ and the activation energy is 10. kJ/mol for the gas-phase reaction

$\text{NO(g})+{\text{O}}_{\text{3}}\text{(g)}\stackrel{}{\to }{\text{ NO}}_{\text{2}}(\text{g})+{\text{O}}_{\text{2}}(\text{g})$

which is important in the chemistry of stratospheric ozone depletion.

1. (a) Calculate the rate constant for this reaction at 370. K.
2. (b) Assuming that this is an elementary reaction, calculate the rate of the reaction at 370. K if [NO] = 0.0010 M and [O₃] = 0.00050 M.
