AI Generated Solution

To calculate the time taken for three-fourths of a first-order reaction to complete, we can follow these steps: ### Step 1: Understand the concept of half-life in first-order reactions For a first-order reaction, the half-life (t₁/₂) is given by the formula: \[ t_{1/2} = \frac{0.693}{k} \] where \( k \) is the rate constant. ### Step 2: Calculate the half-life ...
