Would anyone be able to explain this to me? I know the correct answer is B, but I have no idea why and can't find any online resources for it.
Which reaction is not used to make a Hess cycle for the following reaction? C2H4 + H2O --> C2H5OH A: fH ethanol B: cH ethene C: cH hydrogen D: fH ethene
so enthalpy of formation is used to make the product and ethene. enthalpy of combustion is used to calculate formation of H20. so combustion of ethene isnt needed
