"The table shows the thermodynamic data for a reaction. Thermodynamic Data Energy of the Reactant Energy of the ProductsActivation Energy −120 kJ−340 kJ−80 kJ Which of the following statements explains if the reaction is endothermic or exothermic?"
a The change in enthalpy is +220 kJ, so it is an endothermic reaction.
b The change in enthalpy is −220 kJ, so it is an exothermic reaction.
c The activation energy is lower than the change in enthalpy, so it is an exothermic reaction.
d The activation energy is higher than the change in enthalpy, so it is an endothermic reaction.
