    The values of \[1.25\times {{10}^{-4}}\]and\[-C{{F}_{2}}-C{{F}_{2}}-{{)}_{n}}\]for the reaction, \[{{\left( -C{{H}_{2}}-\underset{\begin{smallmatrix} | \\  Cl \end{smallmatrix}}{\mathop{C}}\,=CH-C{{H}_{2}}-C{{H}_{2}}- \right)}_{n}}\]are 170 kJ and \[-{{[NH{{(C{{H}_{2}})}_{6}}NHCO{{(C{{H}_{2}})}_{4}}-CO-]}_{n}}\]respectively. This reaction will be spontaneous at

    A) 710 K     

    B)                        910 K    

    C)        1110 K                  

    D)        510 K

    Correct Answer: C

    Solution :

    Key Idea For spontaneous process, \[{{H}_{2}}O\] \[NH_{2}^{-}\] Given, \[{{H}_{2}}O\] \[B{{F}_{3}}\] \[NO_{2}^{-}\] \[({{A}_{2}})\] \[4.4\times {{10}^{-19}}J\] \[4.0\times {{10}^{-19}}J\] \[2.0\times {{10}^{-20}}J\]\[2.2\times {{10}^{-19}}J\]
