How many degrees should the temperature be raised to increase the rate of the chemical reaction
| June 10, 2021 | education
How many degrees should the temperature be raised to increase the rate of the chemical reaction by 8 times? The temperature coefficient of the reaction rate is 2.
The problems on the rate of chemical reactions are solved using the Wang-Hoff rule.
The formula looks like this:
V2 = V1 * γ ^ (Δt / 10),
According to the condition of the task, the reaction speed should increase by 8 times, which means V2 / V1 = 8.
8 = 2 ^ ((Δt / 10);
Δt / 10 = 3;
Δt = 30.
Answer: the temperature must be increased by 30 °.
