(b) $Q_{\text{c}}=\frac{{\left[{\text{NO}}_{\text{2}}\right]}^{\text{2}}\left[{\text{Cl}}_{\text{2}}\right]}{{\left[{\text{NClO}}_{\text{2}}\right]}^{\text{2}}}$

(c) $Q_{\text{c}}=\frac{\left[{\text{HgI}}_{\text{4}}^{\text{2-}}\right]}{\left[{\text{Hg}}^{\text{2+}}\right]{\left[{\text{I}}^{\text{-}}\right]}^{\text{4}}}$

(d) $Q_{\text{c}}=\frac{{\left[\text{NO}\right]}^{\text{2}}\left[{\text{Br}}_{\text{2}}\right]}{{\left[\text{NOBr}\right]}^{\text{2}}}$
