(B) The decomposition of hydrogen peroxide is a first-order reaction.For a first-order reaction, the half-life $(t_{1/2})$ is given by the formula: $t_{1/2} = \frac{0.693}{k}$.Given the rate constant $k = 0.0204 \text{ min}^{-1}$.Substituting the value of $k$ in the formula: $t_{1/2} = \frac{0.693}{0.0204 \text{ min}^{-1}}$.$t_{1/2} \approx 33.97 \text{ min}$.
