The reaction described by this equation O_3(g) + NO(g) rightarrow O_2(g) + NO_2(g) has the...


The reaction described by this equation

{eq}O_3(g) + NO(g) \rightarrow O_2(g) + NO_2(g) {/eq}

has the following rate law at 310 K.

rate of reaction = {eq}K[O_3][NO]; k = 3.0 \times 10^6 M^{-1} \cdot s^{-1} {/eq}

a. Given that {eq}[O_3] = 8.0 \times 10^4 {/eq} M and {eq}[NO] = 8.0 \times 10^{-5} {/eq} M at t = 0, calculate the rate of the reaction at t = 0.

b. What is the overall order of this reaction?

A. 0

B. 1

C. 2

D. 3

Rates of Reaction

The rate of a chemical reaction is often written in terms of a rate constant and the concentrations of the reagents. The respective powers to which the concentrations of the species are raised are known as the orders of the reaction with respect to that species. The overall order is the sum of all the powers.
