Question

The temperature coefficient of a certain reaction is found to be 3.If the temperature changes from 25C to 55C, then how many times greater the new rate of reaction will be

Answer 1

The new rate of reaction will be 27 times greater than the old rate of reaction.

We know that the rate of reaction is given by,

K = μ^(T/10)

where μ = temperature co-efficient

K = rate of reaction at temperature T

Hence we have,

K₂/K₁ =  μ^(T₂-T₁/10)

= 3^(55-25/10)

= 3^30/10

=27

Hence the rate of reaction increases by 27 times.

Answer 2

Answer:

Tx =3

T=55-25=30

K2/K1= Tx ^ ( t2 - t1/10 )

3*(55-25/10)
