Chemical Kinetics Question 24

Question: The rate constant is given by the equation $ k=pz{e^{-E/RT}} $ . Which factor should register a decrease for the reaction to proceed more rapidly [MP PET/PMT 1998]

Options:

A) $ T $

B) $ Z $

C) $ E $

D) $ p $

Show Answer

Answer:

Correct Answer: C

Solution:

When k increases, rate of reaction also increases, $ k=\frac{pz}{{e^{E/RT}}} $ for k to increase p, z, T should increase and E should decrease. ( $ e\approx 2.7 $ ).
