If for an ideal gas reaction 2 {\A}( {\g})+ {\B}( {\g}) \to 2 {\C}( {\g}) the standard internal energy and entropy changes ∆ {\U}^\theta, ∆ {\S}^{†} are -8.80 {\kJ} {\mol}^{-1},-50 {\J} {\K}^{-1} {\mol}^{-1} respectively at 300 {\K}, which of the following statements is correct?

Correct Answer is : ∆G⊖=3.71kJmol−1, the reaction is non-spontaneous

∆ {\G}^{⊖}=-3.71 {\kJ} {\mol}^{-1}, the reaction is non-spontaneous

∆ {\G}^{⊖}=3.71 {\kJ} {\mol}^{-1}, the reaction is spontaneous

∆ {\G}^{⊖}=3.71 {\kJ} {\mol}^{-1}, the reaction is non-spontaneous

∆ {\G}^\theta=-26.29 {\kJ} {\mol}^{-1}, the reaction is spontaneous
