The standard molar enthalpy of combustion, deltacHm, of C2H6 (g) is -1559.8 kJ/mol.

1. Use some of the following data to calculate the molar enthalpy of formation of C2H6(g) at 298.15 K

2. Calculate the molar enthalpy of combustion of ethane at 500K

Table provided gives values of standard enthalpy of formation values at 298.15 K

Substance deltafH (kJ*mol^-1) Cpm (J*K^-1*mol^-1)
CO2 (aq) -413.8 N/A
CO2 (g) -393.51 37.11
H2O (l) -285.83 75.291
H2O(g) -241.82 33.58
C2H6(g) to be determined 52.38
