The initial concentration of ethyl acetate is `0.85 mol L^(-1)` . Following the acid catalysed hydrolysis the , concentrations of ester after 30 min and 60 min of the reaction are respectively ` 0.8 and 0.754 mol L^(-1)` . Calculate the rate constant and pseudo rate constant.

Explanation

To solve the problem, we need to calculate the rate constant (K') and the pseudo rate constant (K) for the acid-catalyzed hydrolysis of ethyl acetate.

### Step-by-Step Solution:

1. **Identify the Initial Concentration and Concentrations at Given Times:**
- Initial concentration of ethyl acetate, \( [A_0] = 0.85 \, \text{mol L}^{-1} \)
- Concentration after 30 minutes, \( [A_{30}] = 0.80 \, \text{mol L}^{-1} \)
- Concentration after 60 minutes, \( [A_{60}] = 0.754 \, \text{mol L}^{-1} \)
