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?
- The enthalpy of CO2 is greater than the reactants.
- E2 - E1 is negative.
- Graphite and diamond have equal enthalpy.
- Both reactions are exothermic.
