A.) the standard enthalpy of formation of the reaction C2H4(g)+H2O(l)=C2H5OH(l) B.) Use standard enthalpies of formation to calculate the standard enthalphy change of: the reaction of methane gas, CH4, with chlorine rine to form liquid chloroform, CHCl3. Gaseuous hydrogen chloridee is the other product. C.) Use standard enthalpies of formation to calculate the standard enthalphy change of PCl3(g)+HCl(g)=PCl5(g)+H2(g)

standard enthalpy change of formation

a. Define standard enthalpy change of formation.b. Calculate the standard enthalpy change of formation of methane from the following standard enthalpy changes of combustion:carbon = –394 kJ mol–1hydrogen = –286 kJ mol–1methane = –891 kJ mol–1c. Calculate the standard enthalpy change of combustion of methane using the following bond energies:E(C — H) = +412 kJ mol–1E(O — O) = +496 kJ mol–1E(C — O) = +805 kJ mol–1E(O — H) = +463 kJ mol–1

Consider aluminum and oxygen. In their natural states, their standard enthalpy of formation (i.e., the energy of formation at RTP) is zero. Every kilogram of aluminum has (at RTP) an entropy of 1.05 kJ/K, whereas every kilogram of oxygen has an entropy of 6.41 kJ/K. Aluminum burns fiercely, forming an oxide (Al2O3) and releasing energy. The standard enthalpy of formation of the oxide is –1.67 GJ/kmol. The entropy of the oxide is 51.0 kJ/K per kilomole. According to the second...
