Study the following two reactions. Select all that apply.

C (graphite) + O2 (g) → CO2 (g) + 94.05 kcal

C (diamond) + O2 (g) → CO2 (g) + 94.50 kcal

What could you infer from the information given above?

a The enthalpy of CO2 is greater than the reactants.

b E2 - E1 is negative.

c Graphite and diamond have equal enthalpy.

d Diamond must have lower internal energy.
