| **How many times will the reaction rate increase, the temperature coefficient of which is equal to 2, when the temperature rises from 200C to 50C ..**

1. Let’s use van’t Hoff’s rule:

v2 = v1 * γ ^ ((T2 – T1): 10);

v2 = v1 * γ ^ (ΔT: 10);

2.Calculate the difference in temperature change:

ΔT = 50 – 20 = 30 ° C;

3.For convenience, let us assume that the initial rate is 1, calculate what value the reaction rate will take after increasing the temperature:

v2 = 1 * 2 ^ (30: 10) = 2 ^ 3 = 8:

4. Establish the ratio of the acquired speed to the initial one:

v2: v1 = 8: 1 = 8, which means the reaction speed will increase by 8 times.
