# For the reaction R → P, the concentration of a reactant changes from 0.03M to 0.02M in 25 minutes. Calculate the average rate of reaction using units of time both in minutes and seconds.

Answer :

Given-

Initial concentration(R_{1}) = 0.03M

Final concentration(R_{2}) = 0.02M

Time = 25 mins.

The formula for average rate of the reaction is,

→ Equation 1

∵ {R} = (R_{2})-( R_{1}), the equation 1 is written as,

= 4 × 10^{-4} mol L^{-1} min^{-1}

The average rate of reaction in seconds is given by,

=

(dividing by 60 to convert minutes to seconds)

= 6.6 × 10^{-6} mol L^{-1} s^{-1}

__The average rate of the reaction in minutes is__ __4 × 10 ^{-4} mol L^{-1} min^{-1} and in seconds is 6.6 × 10^{-6} mol L^{-1} s^{-1}__
