activation energy units

Postby Kyle Rex 1K » Thu Mar 12, 2020 4:47 pm

does activation energy depend on the number of moles of something or is it a constant value for a certain reaction?

Activation energy does not depend on the number of moles. If the number of moles goes up, then total energy goes up, as evidenced by the activation energy, but activation energy itself does not have anything to do with it.

To add on, the units of activation energy are joules per mole since this cancels out with the constant R.

The units for activation energy are joules/mol. Joules gives the energy and the moles makes it standard for the reaction.
