The activation energy for a simple chemical reaction A arrow B is...
The activation energy for a simple chemical reaction is in forward direction. The activation energy for reverse reaction:
Options
- Ais negative of
- Bis always less than
- Ccan be less than or more
- Dis always double of
Correct answer
C. can be less than or more
Step-by-step solution
The activation energy for the reverse reaction, , is the difference between the product energy and transition state at the peak of the diagram. is the difference between the potential energy of the reactant and the potential energy of the product.
Related Theory
In a reversible reaction of bi-molecular type the activation energy for forward reaction is positive. Whereas, for the backward reaction activation energy is negative.
