Select all the true statements about activation energies.
The activation energy is independent of the overall free energy change of the reaction.
The activation energy is the energy difference between the ground states of the reactant and the product.
The lower the activation energy, the higher the reaction rate.
Exergonic reactions have negative activation energies.
The activation energy is increased by adding a catalyst.
In an endergonic reaction the activation energy in the forward direction is larger than the activation energy in the reverse direction.
The larger the activation energy, the more exergonic the reaction.
The activation energy is the difference between a ground state and the transition state free energies.
