1.	Predict which of the following reaction will have appreciable concentration of reactants and products : (a)Cl_(2(g)) hArr 2Cl_((g)) , K_c=5xx10^(-39) (b) Cl_(2(g)) + 2NO_((g)) hArr 2NOCl_((g)) , K_c=3.7xx10^8 (c)Cl_(2(g)) + 2NO_(2(g)) hArr 2NO_2Cl_((g)) , K_c= 1.8
Answer» Solution :(a)`K_c=5xx10^(-39)` , the value of K is very small, so = products will REMAIN very less at the equilibrium. (B) `K_c = 3.7 XX 10^8`, the value of K is more, so theconcentration of products of reactants will be high than the concentrations of products. (c) `K_c= 1.8`, the value of `K_c`, is in-between `10^(-3)` and `10^(3)` so at the equilibrium the concentration of reactants and products are COUNTABLE.
