    AG for a reaction is 46.06 kcal/mole, K for the reaction at 300k is:

    A) \[{{10}^{8}}\]                        

    B)  \[{{10}^{2222}}\]

    C) \[{{10}^{33.33}}\]                  

    D)  \[None\]

    Correct Answer: C

    Solution :

    [c] \[{{10}^{3333}}\] \[\Delta \,{{G}^{{}^\circ }}=46.05Kcal/mole\] \[=46.06\times 1000\times 4.184J\,mo{{l}^{-1}}\] \[A{{G}^{{}^\circ }}=-\,RT\ell n\,{{K}_{p}}\] \[=-2.303\text{ }RT\text{ }log\,{{K}_{p}}\] \[46.06\times 1000\times 4.184=\] \[-\,2.303\times 8.314\times 300\text{ }log\] \[log\text{ }Kp=-33.55\] \[or\text{ }{{K}_{p}}={{10}^{-33-55}}\]
