    A)                 \[\Delta {{G}^{o}}=-nFE_{cell}^{o}\]        

    B)                 \[\Delta {{G}^{o}}=+nFE_{cell}^{o}\]

    C)                 \[\Delta {{G}^{o}}=-2.303RT\,nFE_{cell}^{o}\]   

    D)                 \[\Delta {{G}^{o}}=-nF\,\log {{K}_{C}}\]

    Correct Answer: A

    Solution :

                    \[\Delta {{G}^{o}}=-2.303RT\,\log {{K}_{eq}}\] or \[\Delta {{G}^{o}}=-nFE_{cell}^{o}\]
