Order Of Reaction

To determine the rate of a first-order reaction where the concentration reduces from 0.03 mol L^-1 to 0.02 mol L^-1 in 25 minutes, we use the first-order kinetics formula:

Formula:

• Rate constant (k):

Given:

Calculation:

1. Calculate rate constant :
   
3. Substitute to find :
   

Find Rate of Reaction:

• The rate of reaction for a first-order process can be expressed as:

However, if detailed steps confirmed:

Thus, the rate is confirmed as: mol L s .
