Chemical Kinetics Question 245
Question: The rate of a reaction is doubled for every $ 10^{o} $ rise in temperature. The increase in reaction rate as a result of temperature rise from $ 10^{o} $ to $ 100^{o} $ is [KCET 1993; Kerala PET 2002; MP PET 2003]
Options:
A) 112
B) 512
C) 400
D) 614
Show Answer
Answer:
Correct Answer: B
Solution:
$ \frac{k_{t}+10}{K_{t}}=\frac{r_{t}+10}{r_{t}}=2 $ For an increase of temperature to $ 90^{o}C $ i.e. 9 times, the rate increases by $ 2^{9} $ times i.e. 512.
