The equilibrium constant, Kc for the reaction
2NOCL(g) ? 2NO(g) + Cl2(g)
at 308 K is 1.6 x 10 -5
at this temperature, does the reaction favor products orreactions?
b) caculate Kp for this reaction at this temperature.
c) calculate the equlibrim constant at this temperature forthe reaction.
2NO(g) + Cl2(g) ?2NOCL(g)

    For the reaction -:
    2NOCl(g) ? 2NO(g) + Cl2(g)
    the equiliconstant is very less 1.6 x 10 -5so the reaction is unfavorable in the forward direction
    and the formation of reactants is thus favorable.
    b ) Kp =Kc(RT)?n
               = 1.6 x 10 -5 (0.0821*308)1=4.045*10-4
    c) Equilibrium constant for thereaction
            2NO(g) +Cl2(g) ?2NOCl(g)
       Kc' = 1/Kc = 1/1.6 x 10-5 = 62500 = 6.25*104
    Hope thishelps!
