As with the products, use the standard heat of formation values from the table, multiply each by the stoichiometric coefficient, and add them together to get the sum of the reactants. ΔHºf C 2 H 2 = +227 kJ/mole. vpΔHºf C 2 H 2 = 2 mol (+227 kJ/mole) = +454 kJ. ΔHºf O 2 = 0.00 kJ/mole. Ethane is an organic chemical compound with chemical formula C 2H 6. At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by-product of petroleum refining. Its chief use is as feedstock for ethylene production. Related compounds may be formed by replacing a hydrogen atom with another functional group; …
