Standard enthalpy and standard entropy change for the oxidation of \[\text{N}{{\text{H}}_{\text{3}}}\]at 298 K are \[-382.64\,\text{kJ}\,\text{mo}{{\text{l}}^{-1}}\]and\[-145.6\,\text{J}\,\text{mo}{{\text{l}}^{-1}}\] respectively. Standard Gibbs energy change for the same reaction at 298 K is

A) \[+\,339.3\text{ kJ}\,\text{mo}{{\text{l}}^{-1}}\]    

B) \[~-\text{ }439.3\text{ kJ}\,\text{mo}{{\text{l}}^{-1}}\]

C) \[-\text{ }339.3\text{ kJ mo}{{\text{l}}^{-1}}\]    

D) \[~-\text{ }393.3\text{ kJ mo}{{\text{l}}^{-1}}\]
