WebC-C enthalpy = 348 kJ/mol C-H enthalpy = 413 kJ/mol H-H enthalpy = 436 kJ/mol The way I see it, H-H has to break, C-C has to break, and then two C-H bonds have to form. (Units omitted) Therefore, should the answer be: 413 ⋅ 2 − 348 − 436 = 42 kJ/mol So then it has to be an endothermic reaction. Is this correct, or am I wrong? physical-chemistry WebEthene and hydrogen gas reaction in the presence of nickel or platinum or palladium catalyst will give ethane as the product.
