Write the mathematical expression relating the variation of rate constant of a reaction with temperature.

Explanation

To write the mathematical expression relating the variation of the rate constant of a reaction with temperature, we can use the Arrhenius equation. Here’s a step-by-step solution:

### Step 1: Write the Arrhenius Equation
The Arrhenius equation is given by:

\[ k = A e^{-\frac{E_a}{RT}} \]

Where:
...
