Question -

What is the effect of temperatureon the rate constant of a reaction? How can this temperature effect on rateconstant be represented quantitatively?



Answer -

The rate constant is nearlydoubled with┬аa rise intemperature by 10┬░ for a chemical reaction.

Thetemperature effect on the rate constant can be represented quantitatively byArrhenius equation,

where,┬аk┬аisthe rate constant,

A is theArrhenius factor or the frequency factor,

R is the gas constant,

T┬аis the temperature, and

Ea┬аis the energy of activation for thereaction
