Which of the following statements below is true concerning the activation energy for a reaction? O The greater the activation energy, the faster the reaction. The activation energy speeds up a reaction by finding an alternate pathway. E, is the difference in energy between reactants and products. O E, is the difference in energy between reactants and transition state. E, decreases with increasing temperature.
