What is the temperature coefficient of reaction if, when the temperature rises from 30

| What is the temperature coefficient of reaction if, when the temperature rises from 30 to 60 degrees, the reaction rate increases 8 times.
From school we know that with an increase in temperature for every 10 °, the reaction rate increases by 2-4 times.
This dependence looks as follows:
K2 / K1 = γ ^ ΔT / 10.
We know that for any reaction order K ~ -dC / dt, and the derivative of the concentration with respect to time is nothing but the reaction rate – V.
V2 / V1 = γ ^ ΔT / 10.
V2 / V1 = 8.
T1 = 30 °.
T2 = 60 °.
ΔT = 60-30 = 30 °.
8 = γ ^ 30/10.
8 = γ 3.
(3) sqrt (8) = (3) sqrt (γ 3) (we take the third root from the left and right sides).
2 = γ.
