In an exothermic reaction, products have [ ] enthalpy than reactants, so ΔH\Delta HΔH is [ ].
A
In an exothermic reaction, products have higher enthalpy than reactants, so ΔH\Delta HΔH is negative.
B
In an exothermic reaction, products have lower enthalpy than reactants, so ΔH\Delta HΔH is positive.
C
In an exothermic reaction, products have higher enthalpy than reactants, so ΔH\Delta HΔH is positive.
D
In an exothermic reaction, products have lower enthalpy than reactants, so ΔH\Delta HΔH is negative.
