77.In the early days of automobiles, illumination at night was provided by burning acetylene, C2H2. Though no longer used as auto headlamps, acetylene is still used as a source of light by some cave explorers. The acetylene is(was) prepared in the lamp by the reaction of water with calcium carbide, CaC2:CaC2(s)+2H2O(l)⟶Ca(OH)2(s)+C2H 2(g). Calculate the standard enthalpy of the reaction. TheΔHf°of CaC2is −15.14 kcal/mol.
