The Enthalpy of Combustion of Acetylene C₂H₂ Is Described by $\rarr$

question 111

Short Answer

The enthalpy of combustion of acetylene C₂H₂ is described by
C₂H₂(g)+ (5/2)O₂(g) $\rarr$ 2CO₂(g)+ H₂O(l), $\Delta$ H°_rxn= -1299 kJ/mol
Calculate the enthalpy of formation of acetylene, given the following enthalpies of formation
$\Delta$ H°_f[CO₂(g)] = -393.5 kJ/mol
$\Delta$ H°_f[H₂O(l)] = -285.8 kJ/mol
