Question

Enthalpy of combustion of ethane and ethene are -1560 and -1409 and if the enthalpy of combustion of hydrogen is -286 then calculate the enthalpy of the reaction

Answer 1

Answer:

Calculate the heat of combustion of ethane, as described in the equation C2H6(g) + 3½O2(g) → 2CO2(g) + 3H2O(l), given the heats of formation of ethane gas, carbon dioxide gas and water liquid are –84.7 kJ mol-1, -393.5 kJ mol-1 and –285.8 kJ mol-1 respectively. Answer: C2H6(g) + 3½O2(g) → 2CO2(g) + 3H2O(l) ΔHc
