The temperature coefficient of some reaction is 3. How many times will the reaction rate increase

The temperature coefficient of some reaction is 3. How many times will the reaction rate increase if this reaction proceeded under normal conditions, and then under standard conditions?

According to the Van’t Hoff rule, when the temperature of the reaction changes, its speed will change 2-4 times for every 10 degrees
v1, v2 – reaction rates under normal and under standard conditions, respectively.
γ – temperature coefficient.
T1, T2 – temperatures under normal and under standard conditions, respectively.
T1 = 273 K, T2 = 298 K
v2 / v1 = γ ^ ((T2 – T1) / 10) = 3 ^ ((298 – 273) / 10) = 3 ^ 2.5 = 15.59
The reaction speed will increase 15.59 times
