For this particular reaction, the combustion of a settling. B. Ch. Mg(HCO3)2 ", An authentic dinosaur bone is being offered for sale on the Internet. Hrxn = 2 mol Hf(CO(g)) + 1 mol Hf(HO(l)) - 1 mol Hf(CH(g)) - 1 mol Hf(O(g)), 1 mol Hf(CH(g)) = 2 mol Hf(CO(g)) + 1 mol Hf(HO(l)) - Hrxn - 1 mol Hf(O(g)), 1 mol Hf(CH(g)) = 2 mol (-393.5 kJ/mol) + 1 mol (-285.8 kJ/mol) - (-1299 kJ) - 1 mol (0 kJ/mol), The enthalpy of formation of acetylene is 226.2 kJ/mol, C2H2 (g) + (5/2)O2 (g) 2CO2 (g) + H2O (l) Heat of Reaction (Rxn) = -1299kJ/mol, Standard formation [CO2 (g)]= -393.5 kJ/mol, Standard formation [H2O (l)] = -285.8 kj/mol, Step 3: Calculate the enthalpy of formation of acetylene.
