Use the Bond Enthalpy Data Given to Estimate the Heat $\equiv$

question 38

Multiple Choice

Use the bond enthalpy data given to estimate the heat released when 25.0 g of acetylene gas, C₂H₂, burns in excess oxygen to yield carbon dioxide and water vapor at 25°C. BE(C-C) = 347 kJ/mol
BE(C $\equiv$ C) = 812 kJ/mol
BE(C=O in CO₂) = 799 kJ/mol
BE(C-H) = 414 kJ/mol
BE(O-H) = 460 kJ/mol
BE(O=O) = 498.7 kJ/mol

• A)1180 kJ
• B)447 kJ
• C)364 kJ
• D)1230 kJ
• E)16.8 kJ
