6.The combustion reaction of the amino acid glycine (NH2CH2COOH, solid) has a standard enthalpy of –969 kJ/mol at 298K, and a standard molar entropy of +103.5 J/mol×K. In reference to the formation of glycine, calculate the values of the standard molar: a)Enthalpy (D f Hʅ) b)Entropy (D f Sʅ) c)Gibbs Free energy
