Draw a graph which is used to calculate the activation energy of a reaction. Give the appropriate expressions used to calculate the activation energy graphically.

Explanation

To calculate the activation energy (Ea) of a reaction graphically, we can use the Arrhenius equation, which relates the rate constant (k) of a reaction to the temperature (T) and activation energy. Here’s a step-by-step solution to the question:

### Step 1: Understand the Arrhenius Equation
The Arrhenius equation is given by:
\[ k = A e^{-\frac{E_a}{RT}} \]
where:
- \( k \) = rate constant
- \( A \) = Arrhenius constant (frequency factor)
