Chemical Kinetics Question 331

Question: When a biochemical reaction is carried out in laboratory in the absence of enzyme then rate of reaction obtained is $ {10^{-6}} $ times, then activation energy of reaction in the presence of enzyme is

Options:

A) $ \frac{6}{RT} $

B) different from $ E_{a} $ obtained in laboratory,

C) P is required

D) can’t say anything

Show Answer

Answer:

Correct Answer: B

Solution:

[b] The presence of enzyme (catalyst) increases the speed of reaction by lowering the energy barrier, i.e., a new path is followed with lower activation energy. Here $ E_{T} $ is the threshold energy. $ E_{a} $ and $ E_{a1} $ is energy of activation of reaction in absence and presence of catalyst respectively.
