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

Answer» Solution :Average rate `=-(DELTA[R])/(Deltat)=-([R]_(2)-[R_(1)])/(t_(2)-t_(1))` `= -(0.02M-0.030M)/(25"minutes")= -(0.01M)/("25 minutes")=4xx10^(-4)" MOL litre"^(-1)" minutes"^(-1)` `=(-0.1M)/(25xx60s)=6.66xx10^(-6)" mol litre"^(-1)" SECOND"^(-1)`. |
