The rate constant of a reaction is `1.5xx10^7s^-1` at `50^@C` and `4.5×10^7s^ −1` at `100^@C`. Calculate the Arrhenius parameter for the reaction.

Text Solution

Verified by Experts

From relation.
`"log" K_2/K_1=E_a/(2.303R)[1/T_1-1/T_2]"implieslog"(4.5xx10^7)/(1.5xx10^7)`
`=E_a/(2.303xx8.314)[1/323-1/373]implies"log3"=[E_a//(19.147)]xx50//(323xx373]`
`E_a=(0.4771xx19.147xx323xx373)/50impliesE_a=22.01kj mol^-1`
