Solution

The average rate of reaction is the ratio of the change in concentration of the reactant or the product in the chemical reaction to the time interval. The negative value and positive value of the average rate depending on changes in the concentration.
(1) Change in concentration from 0.03M to 0.02M in 25 minutes.
(2) Decrease in concentration from 0.5 to 0.4 mol/L
in 10 minutes.
The mathematical expression used to calculate the average rate is shown below.
Averagerate=ΔX/Δt
Where,
ΔX is the change in concentration of reactant or product
Δt is the time interval
$A v e r a g e R a t e = \frac{[0.03] - [0.02]}{25}$

$R a t e = 4 \times 10^{- 4} {m i n}^{- 1}$

$R a t e = 6.67 \times 10^{- 6} s^{- 1}$
