The temperature coefficient of a reaction is 2. When the temperature is increased from `30^(@)`C to `90^(@)`C, the rate of reaction is increased by

A

60 times

B

64 times

C

150 times

D

400 times

Text Solution

Verified by Experts

The correct Answer is:
B
Rate of reaction is doubled for every `10^(@)C`rise in temperature. Temperature goes up by `60^(@)`C, So, rate goes up `2^(6)` times i.e., times
