        (a)     Cl_{2}(g)\rightleftharpoons 2Cl(g);K_{c}=5 \times 10^{-39} 
        (b)     Cl_{2}(g) +2 NO(g)\rightleftharpoons 2NOCl(g);K_{c}=3.7 \times 10^{8} 
        (c)     Cl_{2}(g) +2 NO_{2}(g)\rightleftharpoons 2NO_{2}Cl(g);K_{c}=1.8

If the value of K_c is in the range of 10^{-3} to 10^{3}, then the reaction has appreciable concentrations of both reactants and products.

Therefore, the third reaction (c)(K_c=1.8) will have an appreciable concentration of reactants and products.
