If the concentration of OH^$$-$$ ions in the reaction
Fe(OH)_3(s) $$\rightleftharpoons$$ Fe³⁺_(aq) + 3OH^$$-$$_(aq)
is decreased by 1/4 times, then equilibrium concentration of Fe³⁺ will increase by

The dissociation equilibrium of a gass AB₂ can be represented as :
2AB_2(g) $$\rightleftharpoons$$ 2AB_(g) + B_2(g)
The degree of dissociation is x and is small compared to 1. The expression relating the degree of dissociation (x) with equilibrium constant K_p and total pressure P is
