# The reaction described by this equation O_3(g) + NO(g) ---> O_2(g) + NO_2(g) has the following...

## Question:

The reaction described by this equation,

{eq}\rm 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\rm [O_3][NO]; \textit{k} = 3.0 \times 10^6\;M^{-1}s^{-1} {/eq}

a. Given that {eq}\rm [O_3] = 5.0 \times 10^{-4}\;M{/eq} and {eq}\rm [NO] = 8.0 \times 10^{-5}\;M{/eq} 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

## Order of Reaction:

The order of a reaction means the power dependence of the rate of reaction on the concentrations of reactants. The order of a reaction is determined experimentally. It can even be fractional values.
