The rate constants of a reaction at `35^(@)C and 65^(@)C " are " 6.65xx10^(-5)s^(-1) and 2.24xx10^(-3)s^(-1)` respectively. Calculate the frequency factor of the reaction.

Text Solution

Verified by Experts

`log.(k_(2))/(k_(1))=(E_(a))/(2.303R)xx((T_(2)-T_(1))/(T_(1)T_(2)))`
or, `log.(2.24xx10^(-3))/(6.65xx10^(-5))=(E_(a))/(2.303xx8.314)xx(30)/(308xx338)`
`therefore E_(a)=101.48"kJ.mol"^(-1)`
Now, `k=Ae ^((-E_(a))/(RT)) " or, "6.65xx10^(-5)=Ae^((-101480)/(8.314xx308))`
`therefore A = 1.08xx10^(13)s^(-1)`
