But the problem is , isn’t the entalphy change is only needed for C2H2. Here it gives C2H2 and H2
In the Transformation of carbon and hydrogen to ethyne we need 2 moles of Carbon and 1 mole of hydrogen . The other mole of hydrogen is not used in the reaction and hence the change in enthalpy of that step is zero . I hope you can see in the picture

Is there any easy was to calculate isomers ? It gets so confusing. And , can anyone explain stereoisomerism ( like for the geometric one, should there be 2 same group to depict the cis and trans , or the hydrogen can be considered) ?
