Problem

For the reaction:

\text{H}_2(\text{g}) + \text{Br}_2(\text{g}) \rightarrow 2\text{HBr}(\text{g})

, the experimental data suggests

\text{Rate} = k[\text{H}_2][\text{Br}_2]^{1/2}

The molecularity and order of reaction for the reaction is a. 2 and 2 respectively b. 2 and

1\frac{1}{2}

respectively c.

1\frac{1}{2}

and 2 respectively d. Not Defined and

1\frac{1}{2}

respectively
