In the reaction , if the initial rate of disappearance of A at is , what is the initial rate of appe — Chemical Kinetics Chemistry Question
Question
In the reaction $A + 2B \rightarrow 6C + 2D$, if the initial rate of disappearance of A at $t = 0$ is $2.6 \times 10^{-2} \text{ M s}^{-1}$, what is the initial rate of appearance of C?
Answer: C
💡 Solution & Explanation
Rate of reaction $= -\frac{d[A]}{dt} = +\frac{1}{6}\frac{d[C]}{dt}$. Therefore, $\frac{d[C]}{dt} = 6 \times (-\frac{d[A]}{dt}) = 6 \times 2.6 \times 10^{-2} = 1.56 \times 10^{-1} \text{ M s}^{-1}$.
