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.


Given-


Initial concentration(R1) = 0.03M


Final concentration(R2) = 0.02M


Time = 25 mins.


The formula for average rate of the reaction is,


Equation 1


{R} = (R2)-( R1), 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
