A reactions is of second order with respect to a reactant. How is the rate of reaction affected if the concentration of the reactant is reduced to half?

Explanation

To solve the problem, we need to understand how the rate of a second-order reaction is affected by changing the concentration of the reactant. Let's break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Rate Law for a Second-Order Reaction**:
- For a reaction that is second order with respect to a reactant A, the rate of the reaction (R) can be expressed as:
\[
R = k[A]^2
