For the elementary reaction `2A + B_(2) rarr 2AB`. Calculate how much the rate of reaction will change if the volume of the vessel is reduced to one third of its original volume?

Explanation

To solve the problem, we need to determine how the rate of the reaction changes when the volume of the vessel is reduced to one-third of its original volume. The reaction given is:

\[ 2A + B_2 \rightarrow 2AB \]

### Step 1: Write the Rate Law for the Reaction
For an elementary reaction, the rate law can be directly derived from the stoichiometry of the reaction. The rate law for this reaction can be expressed as:

\[
