For the given reaction, choose the correct expression of K_C from the following:- Fe_( aq )^3++ SCN_( aq )^- ⇌( FeSCN )_( aq )^2+
For the given reaction, choose the correct expression of $\displaystyle \mathrm{K}_{\mathrm{C}}$ from the following :-
$$\mathrm{Fe}_{(\mathrm{aq})}^{3+}+\mathrm{SCN}_{(\mathrm{aq})}^{-} \rightleftharpoons(\mathrm{FeSCN})_{(\mathrm{aq})}^{2+}
$$
Official answer
From NTA’s final answer key for this paper.
(3)
$\displaystyle \mathrm{K}_{\mathrm{C}}=\frac{\left[\mathrm{FeSCN}^{2+}\right]}{\left[\mathrm{Fe}^{3+}\right]\left[\mathrm{SCN}^{-}\right]}$
