. A first order chemical reaction is observed to have a rate constant of
k s-1 at a temperature of 300K and activation energy Ea. Estimate the value of rate constant if the temperature is doubled. (assume activation energy becomes 3Ea):
A. ke2
B. ke-2
C. ke-3/2
D. ke-2/3
Best Answer
Ans:C
Sol: The dependence of rate constant with temperature can be estimated using the Arrhenius equation where
