Explain the effect of concentration on equilibrium using the following experiment:
$Fe^{3+}_{(aq)} + SCN^{-}_{(aq)} \rightleftharpoons [Fe(SCN)]^{2+}_{(aq)}$
(Yellow) (Colourless) (Deep red)
$Fe^{3+}_{(aq)} + SCN^{-}_{(aq)} \rightleftharpoons [Fe(SCN)]^{2+}_{(aq)}$
(Yellow) (Colourless) (Deep red)
- AAddition of $Fe^{3+}$ shifts the equilibrium to the right,increasing red color intensity.
- BAddition of $SCN^{-}$ shifts the equilibrium to the right,increasing red color intensity.
- CBoth $(A)$ and $(B)$ are correct.
- DAddition of $HgCl_2$ shifts the equilibrium to the right.
