Chemical Kinetics Question 244

Question: The temperature coefficient for reaction in which food deteriorates is 2. Then food deteriorates …… times as rapidly at $ 25^{o}C $ as it does at $ 5^{o}C $

Options:

A) Two

B) Four

C) Six

D) Twenty

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 $ 20{}^\circ C $ i.e. 2 times, the rate increase by $ 2^{2} $ times, i.e. 4 times.
