Question

Predict which of the following reactions will have appreciable concentration of rectants 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_(2)Cl(g), K_(c)=1.8`

Answer 1

If the value of Kc lies between `10^(-3)` and `10^(3)`, a reaction has appreciable concentration of reactants and products. Thus, the reaction given in (c) will have appreciable concentration of reactants and products.
