Question

Define complex reaction. In a reaction, $2 A \to P r o d u c t s$ , the concentration of A decreases from $0.5 m o l L^{- 1}$ to $0.4 m o l L^{- 1}$ in 10 minutes. Calculate the rate during this interval.

Open in App

Solution

$2 A \to P r o d u c t s$ , So Rate can be defined for this reaction as

$R a t e = \frac{1}{2} \frac{[A_{0}] - [A]}{t}$

$R a t e = \frac{1}{2} \frac{[0.5] - [0.4]}{10}$

$R a t e = 5 \times 10^{- 3} m o l L^{- 1} {m i n}^{- 1}$
