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 $ ).
