Chemical Kinetics Question 243

Question: The velocity of the chemical reaction 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 $ 2^{5} $ times, i.e. 32 times.
