### In Arrhenius equation for a certain reaction, the value of A and Ea (activation energy) are 4x 10^13 sec^-1 and 98.6 kJ mole^-1 respectively. At what temperature, the reaction will have specific rate constant 1.1x 10^-3 sec^-1.

Arrhenius equation:

The temperature dependence of rate of a chemical reaction can be accurately explained by Arrhenius equation. It was first proposed by Dutch chemist   J.H. Vant’s Hoff but Swedish chemist Arrhenius provides its physical justification and interpretation.

Where

K= Rate constant

A= Arrhenius constant or frequency factor or pre exponential factor

R= Universal gas constant =25/3 joule per mole per second

Ea= Activation Energy

T= temperature

-Ea/RT= Boltzmann factor or fraction of molecule having equal or greater than Activation energy or fraction of molecule that have kinetic energy greater than activation energy.
