Q. The rate of a chemical reaction doubles for every $10℃$ rise of temperature. If the temperature is raised by 50$℃$, the rate of the reaction increases by about
A) 10 times
B) 24 times
C) 32 times
D) 64 times
Explanation
(c)
For every $10℃$ rise of temperature, rate is doubled. Thus, temperature coefficient of the reaction=2
When temperature is increased by $50℃$, rate becomes
=$2^{50/10} = 2^{5}$ times=32 times
