At `27^(@)C` in the presence of a catalyst, the activation
?energy of a reaction is lowered by 2 kcal. Calculate
by how much the rate of reaction will increase ?

Explanation

To solve the problem of how much the rate of reaction will increase when the activation energy is lowered by 2 kcal in the presence of a catalyst, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Arrhenius Equation**:
The rate constant \( k \) of a reaction can be expressed using the Arrhenius equation:
\[
k = A e^{-\frac{E_a}{RT}}
