The below chemical reaction has a -224.9 kJ/mol change in Enthalpy and a -74.8 J/K Entropy change. What is the value of Gibbs Free Energy (in kJ/mol)...

The below chemical reaction has a -224.9 kJ/mol change in enthalpy...see the rest of the question below.

The below chemical reaction has a -224.9 kJ/mol change in Enthalpy and a -74.8 J/KEntropy change. What is the value of Gibbs Free Energy (in kJ/mol) at a temperatureof 946 Kelvin? Note: Actual values for real molecules different.2 H2 (g) + 02 (g) --> 2 H20 (1)
