For a certain reaction, the activation energy is 52.1 kj/mole. by what ratio will the rate constant change if the temperature is decreased from 175c to 75c?

The value of the ratio of the rate constant is

Explanation:

Given that,

Energy = 52.1 kJ/mole

Initial temperature = 175°C

Final temperature = 75°C

We need to calculate the ratio of the rate constant change

Using formula of rate constant

Where. T₁= initial temperature

T₂ = final temperature

E = energy

R = gas constant

Put the value into the formula

Hence, The value of the ratio of the rate constant is
