Chemical Kinetics Question 101
Question: The rate of reaction between $ A $ and $ B $ increases by a factor of 100, when the concentration of $ A $ is increased 10 folds. The order of reaction with respect to $ A $ is [CPMT 1985]
Options:
A) 10
B) 1
C) 4
D) 2
Show Answer
Answer:
Correct Answer: D
Solution:
$ r=K{{[A]}^{n}},100r=K{{[10A]}^{n}} $ Thus $ \frac{1}{100}={{( \frac{1}{10} )}^{n}} $ or n = 2
