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?

Looking at both reactions, we can see that the combustion of carbon, graphite or diamond, leads to the formation of carbon dioxide and energy. Since energy is a product of the reaction, we known that this is an exothermic reaction. The value of the change in enthalpy, ΔH, will be negative.

A negative value of ΔH in each exothermic reaction suggests that the carbon dioxide product is at a lower energy than the reactants. And since more energy is released in the combustion of diamond compared to graphite, we know that diamond has a higher internal energy than graphite.

The reaction will shift to the right

The answer should be vaporization
