What is the effect of temperature on the rate constant of a reaction?
How can this temperature effect on rate constant be represented quantitatively?
How can this temperature effect on rate constant be represented quantitatively?
Solution:
The rate constant increases with increase in temperature and becomesalmost double for every 10° increase in temperature. Swedish chemist,Arrhenius derived a quantitative relation between rate of reaction andtemperature. According to Arrhenius,
k = A e −
or,log k = log A − E a R T
