Calculate the G for thisreaction: 2C 2 H 6(g) +7O 2(g) -> 4CO 2(g) +6H 2 O (g) ?

Question

Calculate the G for thisreaction:                                                                                       2C2H6(g)+7O2(g)   ->   4CO2(g) +6H2O(g)                  ???????? Calculate the G for thisreaction:                                                                                       2C2H6(g)+7O2(g)   ->   4CO2(g) +6H2O(g)                  ????????

Explanation / Answer

2C2H6(g)+ 7O2(g)  ->    4CO2(g) +6H2O(g)          G = 4GCO2 +6GH2O - 2GC2H6 -7GO2 after looking up in the table the values of G foreach reactant G = (4 mol)(-394.4 kJ/mol) + (6 mol)(-228.57 kJ/mol) - (2mol)(-32.89 kJ/mol) - (7 mol)(0 kJ/mol) G = -2883 kJ :-|
