Chemical Kinetics Question 70
The velocity of the chemical reaction approximately doubles every $ 10^{o}C $ rise of temperature. If the temperature is raised by $ 50^{o}C $ , the velocity of the reaction increases to about
Options:
A) 32 times
B) 16 times
C) 20 times
D) 50 times.
Show Answer
Answer:
Correct Answer: A
Solution:
$ \frac{K_{t}+10}{K_{t}}=\frac{r_{t}+10}{r_{t}}=2 $ ; For an increase of temperature to $ 50^{o}C $ , i.e. 5 times, the rate increases by $ 5^{2} $ times, i.e. 25 times.
