k, temperature, and activation energy

Postby Noor_Burney_1L » Sun Feb 26, 2017 11:02 pm

Why is it that at a higher temperature, there are more molecules that have a greater energy, E, than activation energy, Ea?

At higher temperatures, molecules are moving a lot faster because there is more energy in the environment (temperature is the measure of heat, which is energy in the environment). Because of this, they are more likely to be able to collide at the required energy level

The more heat something has, the more energetic it is. Molecules must reach a certain energy before they are able to react and that point is called the activation energy Ea.
