(B) For a zero order reaction,the half-life $(t_{1/2})$ is given by the formula:$t_{1/2} = \frac{[A]_0}{2k}$Where $[A]_0$ is the initial concentration and $k$ is the rate constant.Rearranging for $k$:$k = \frac{[A]_0}{2 \times t_{1/2}}$Given $[A]_0 = 0.02 \; M$ and $t_{1/2} = 100 \; s$:$k = \frac{0.02}{2 \times 100} = \frac{0.02}{200} = 1.0 \times 10^{-4} \; mol \; L^{-1} s^{-1}$
