Which of the following statements explains if the reaction is endothermic or exothermic?
The change in enthalpy is +180 kJ, so it is an endothermic reaction.
The change in enthalpy is −180 kJ, so it is an exothermic reaction.
The activation energy is lower than the change in enthalpy, so it is an exothermic reaction.
The activation energy is higher than the change in enthalpy, so it is an endothermic reaction.
