Question -

The concentration of a reactant changes from .03M to .02M in 25 minutes. The average rate of reaction, using time in seconds is

Options:

A .

0.4 \times 10^{- 3} m o l / l / s

B .

0.024 m o l / l / s

C .

0.24 m o l / l / s

D .

6.67 \times 10^{- 6} m o l / l / s

Answer: Option D
:
D

R a t e = \frac{Δ [R]}{Δ t} = \frac{- (0.02 - 0.03)}{25 \times 60} = 6.67 \times 10^{- 6} m o l / l / s
