    In the equilibrium \[2N{{H}_{3}}\rightleftarrows {{N}_{2}}+3{{H}_{2}},6\] moles of \[N{{H}_{3}}\] is taken in 10 L flask. If concentration of \[{{N}_{2}}\] at equilibrium is \[x\], then concentration of \[N{{H}_{3}}\] at equilibrium is

    A)  \[0.6\,-x\]         

    B)  \[0.6\,-2x\]

    C)  \[0.6\,-\frac{x}{2}\]          

    D)  None is correct

    Correct Answer: B

    Solution :

    Concentration of \[[N{{H}_{3}}]=\frac{6}{10}=0.6\] \[2N{{H}_{3}}\,\,\,\,\,\,\rightleftarrows \,\,\,\,\,\,{{N}_{2}}+3{{H}_{2}}\] \[0.6\] \[0\] \[0\] initial \[0.6-2x\] \[x\] \[3x\] at equilibrium Then, concentration of NH3 at equilibrium will be \[0-2x\].
