I have to find out which is true of exothermic reactions:
- Enthalpy of reactants is greater than enthalpy of products.
- Enthalpy of reactants is equal to the enthalpy of products.
- Enthalpy of reactants is less than enthalpy of products.
- Energy is used in an exothermic reaction.

Yep. An exothermic reaction is essentially telling you that , i.e. the change in enthalpy is negative. So the reactants are at a higher energy state than the products.
