Question : 37
Total: 39
What will be the effect of temperature on rate constant?
Solution:
has been found that for a chemical reaction, with rise in temperatureby 10°, the rate constant is nearly doubled.
The temperature dependence of the rate of a chemical reaction can beaccurately explained by Arrhenius equation.
k = A e − E a ∕ R T
Where A is the Arrhenius factor or the frequency factor. It is also calledpre-exponential factor. It is a constant specific to a particular reaction.R is gas constant and Ea is activation energy measured in joules/mole(J mol– 1 ).
