Question
For the zero order reaction $A \rightarrow P$, the rate constant $K = 10^{-2} \text{ M s}^{-1}$. If the initial concentration of $A$ is $0.3 \text{ M}$, what will be the concentration of $A$ left after $10 \text{ seconds}$?
Answer: B
💡 Solution & Explanation
The integrated rate law for a zero-order reaction is $[A]_t = [A]_0 - Kt$. Given $[A]_0 = 0.3 \text{ M}$, $K = 10^{-2} \text{ M s}^{-1}$, and $t = 10 \text{ s}$. Thus, $[A]_t = 0.3 - (10^{-2} \times 10) = 0.3 - 0.1 = 0.2 \text{ M}$.
