For the reaction RtoP, 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))=-(0.02" M"-0.030" M")/(25" MIN")=-(-0.01" M")/(25" min")=4xx10^(-4)" M min"^(-1)` or `=-(-0.01" M")/(25xx60s)=6.66xx10^(-6)" Ms"^(-1)` |
