How will the rate of a chemical reaction change when the temperature drops from 60

How will the rate of a chemical reaction change when the temperature drops from 60 degrees to 40 degrees, if the temperature coefficient is 3?

To find the change (decrease) in the rate of the reaction under consideration, we apply the formula: k = V1 / V2 = γ ^ (T1 – T2) / 10, where γ is the temperature coefficient (γ = 3); Т1 – initial reaction temperature (Т1 = 60 ºС); Т2 – steady-state reaction temperature (Т2 = 40 ºС).

Let’s perform the calculation: k = γ ^ (T1 – T2) / 10 = 3 ^ (60 – 40) / 10 = 32 = 9 p.

Answer: The speed of the considered reaction will decrease by 9 times.
