QAIPMT-2003-Ch-2674: NEET 2003 Chemistry - Class 12 AIPMT-2003-Ch-2674 Solution: The activation energy for a simple chemical reaction \(A B\) is …
The activation energy for a simple chemical reaction is in forward direction. The activation energy for reverse reaction
Multiple Choice Options
- A is negative of
- B is always less than
- C can be less than or more than
- D is always double of
Step-by-Step Verified Solution
The energy of activation of reverse reaction is
less than or more than energy of activation E a of
forward reaction
_ H = ( E a ) F _ ( E a ) R
Because it depends upon the nature of reaction.
If ( E a ) F > ( E a ) R , reaction is endothermic.
or ( E a ) F < ( E a ) R , reaction is exothermic.
