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

Text Solution

Verified by Experts

Average rate =`-(Delta[R])/(Deltat)=-([R_2]-[R_1])/(Deltat)=-(0.02-0.03)/25`
`=0.01/(25 min)=4xx10^(-4)moL^(-1)min^(-1)`
Average rate`=0.01/(25xx60s)=6.66xx10^(-6)molL^(-1)s^(-1)`
