To solve the problem step by step, we will follow the process outlined in the video transcript and use the first-order reaction kinetics formula. ### Step 1: Understand the given data We are given that a first-order reaction takes 20 minutes for 25% decomposition. This means that after 20 minutes, 25% of the initial concentration \( A_0 \) has reacted. ### Step 2: Calculate the remaining concentration after 25% decomposition If 25% of \( A_0 \) has decomposed, then the remaining concentration of \( A \) after 20 minutes is: \[ ...
