Question:
Predict which of the following reaction will have appreciable concentration of reactants and products:

a) Cl₂ (g) ↔ 2Cl (g)                           Kc = 5 ×10^–39

b) Cl₂(g) + 2NO (g) ↔ 2NOCl (g)       Kc = 3.7 × 10⁸

c) Cl₂ (g) + 2NO₂ (g) ↔ 2NO₂Cl (g)    Kc = 1.8

Answer:

If the value of K_c lies between 10^-3 and 10³, a reaction has appreciable concentration of reactants and products.

Thus, the reaction given in (c) will have appreciable concentration of reactants and products.
