Answer :

a) The concentration of $Fe^{3+}$ at equilibrium is 0.08 m.

b) The concentration of $SCN^{-}$ at equilibrium is 0.26 m.

Solution :

The equilibrium reaction is,

$Fe^{3+}+SCN^-\rightleftharpoons [FeSCN]^{2+}$

Initial concentration 0.230 0.410 0

At equilibrium (0.230 - x) (0.410 - x) x

Given x = 0.150

Therefore,

The concentration of $Fe^{3+}$ = 0.230 - x = 0.230 - 0.150 = 0.08

The concentration of $SCN^{-}$ = 0.410 - x = 0.410 - 0.150 = 0.26

Thus, the concentration of $Fe^{3+}$ at equilibrium is 0.08 m.

The concentration of $SCN^{-}$ at equilibrium is 0.26 m.
