Predict which of the following reaction will have appreciable concentration of reactants and product : ` (a) Cl_(2) (g) hArr 2 Cl (g), K_(c) = 5 xx 10^(-39)`
(b) ` Cl_(2) (g) = 2 NO (g) hArr 2 NOCl (g) , K_(c)= 3*7 xx 10^(8)`
( c ) ` Cl_(2) (g) + 2 NO_(2) (g) hArr 2 NO_(2)Cl (g) , K_(c) = 1*8`

Explanation

For reaction (c ) , as `k_(c)` is neither high nor very low , reactants and product will be present in comparable amounts.
