• A) "x" is the energy of activation, "y" is the heat of the reaction and this reaction is endothermic.
• B) "x" is the energy of activation, "y" is the heat of the reaction and this reaction is exothermic.
• C) "x" is the heat of the reaction, "y" is the energy of activation and this reaction is endothermic.
• D) "x" is the heat of the reaction, "y" is the energy of activation and this reaction is exothermic.
• E) "x" is the heat of the transition state, "y" is the heat of the reaction and this reaction is exothermic.
