Chemical Kinetics Question 77
Consider an endothermic reaction $ X\to Y $ with the activation energies $ E_{f} $ and $ E_{b} $ for the forward and backward reactions, respectively, in general [AIEEE 2005]
Options:
A) $ E_{b}<E_{f} $
B) $ E_{b}>E_{f} $
C) $ E_{b}=E_{f} $
D) There is no definite relation between $ E_{b} $ and $ E_{f} $
Show Answer
Answer:
Correct Answer: A
Solution:
For endothermic reaction ΔH = +ve Then from equation $ \Delta H={E_{{a_{F.R.}}}}-{E_{{a_{B.R.}}}};{E_{B.R.}}<{E_{F.R.}} $
