Question

The rate of reaction is doubled for every 10°C rise in temperature. The increase
in reaction rate as a result of temperature rise from 10°C to 50°C is
(A) 32

(B) 16
(C) 64
(D) 614

​

Answer 1

reaction rate increase by 16 times

Explanation:

Given

The rate of reaction is doubled for every 10°C rise in temperature

T1 = 10°C

T2 = 50°C

reaction rate = ??

Solution

as we know that

K2 / K1 = u ^ ΔT/10

K2 / K1 = u ^ 50 - 10 / 10

K2 / K1 = u ^ 40/10

K2 / K1 = 2⁴

K2 / K1 = 16

rate of reaction will increase by 16 times
