Answer 2

The enthalpy of formation (delta Hf) of carbon dioxide from the reaction of carbon and oxygen is –393.5 kJ/mol

What is enthalpy change of a reaction?

The enthalpy change the of a reaction is the amount of heat given off or absorbed when reactant molecules react to form products molecules.

• Change in enthalpy = energy of bonds formed- energy of bonds broken.

Carbon reacts with oxygen to produce carbon dioxide (CO2 (g), and enthalpy of formation, delta Hf = –393.5 kJ/mol). This means that 393.5 kJ of heat is given off when 1 mole of carbon dioxide is formed from carbon and oxygen.

Therefore, the enthalpy of formation (delta Hf) of carbon dioxide from the reaction of carbon and oxygen is –393.5 kJ/mol
