what happens to the rate when there is two thins that both have the same activation energy and with a constant temperature?
Homework Answers
The activation energy of a particular reaction determines the rate at which it will proceed. The higher the activation energy, the slower the chemical reaction will be.
When two things have same activation energy with a constant temperature then their rate of reactions will also be same.

Consider a system with an activation energy of 50.0 kJ mol-1. Use the Arrhenius equation to determine by what factor the rate constant of the reaction will change when the temperature is doubled, from 200 K to 400 K, all other factors being equal. (In other words, if you double the temperature, what happens to the rate constant k?)
