For the reaction `R to 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.

Text Solution

Verified by Experts

The correct Answer is:
`6.66xx10^(-6)M s^(-1)`
Average rate `=((-)Delta[R])/(Deltat)=((0.03-0.02)M)/(25 mi n)`
`=4xx10^(-4)M mi n^(-1)`
`=(4xx10^(-4)M)/(60s)`
`=6.66xx10^(-6)Ms^(-1)`
