For a chemical reaction A

\to

B, it was found that concentration of B is increased by 0.2 mol L^$-$ in 30 min. The average rate of the reaction is ____________

\times

10^{$-$ 1} mol L^{$-$ 1} h^{$-$ 1}. (in nearest integer)

Accepted Answer

A

\to

B

\begin{matrix} t = 0 & 0 \\ t = 30 min & 0.2 M \end{matrix}

Av. rate of reaction =

- \frac{Δ [A]}{Δ t} = \frac{Δ [B]}{Δ t} = \frac{(0.2 - 0)}{\frac{1}{2}}

= 0.4 = 4 \times 10^{- 1}
