Class 11 NEET Chemistry Equilibrium Questions Part 1

Fe(OH)3(g)⇌Feaq3++3OHaq−
K=

[Fe3+][OH−]3

[Fe(OH3)]

K=[Fe3+][OH−]3(activity of solid is taken unity)
Concentration of OH- ion in the reaction is decreased by 1/4times then equilibrium concentration of Fe3+ will be increased by 64 times in order to keep the value of K constant.
