PLS HELP ASAP I ONLY HAVE 7 min On which of the following factors does the amount of energy absorbed by an endothermic reaction depend?

1. Number of reactants
2. Physical state of the reactant
3. Sum of the potential energy of the reactants and products
4. Difference in the potential energy of the reactants and products
