Question
Question: The rate constant (k') of one reaction is double of the rate constant (k") of another reaction. Then...
The rate constant (k') of one reaction is double of the rate constant (k") of another reaction. Then the relationship between the corresponding activation energies of the two reactions (Ea' and Ea") will be -
A
Ea' >Ea"
B
Ea' = Ea"
C
Ea' <Ea"
D
Ea' = 4Ea"
Answer
Ea' <Ea"
Explanation
Solution
As k' > k'', Ea' < Ea"
∵ Greater the rate constant, less is the activation energy.
