If for \({H_2}_{\left( g \right)} + \frac{1}{2}{S_{2\left( s \right)}}\rightleftharpoons{H_2}{S_{\left( g \right)}}\) and
\(H_{2(g)}+Br_{2(g)}\rightleftharpoons2HBr_{(g)}\)
The equilibrium constants are k1 and k2 respectively, the reaction
\(Br_{2(g)}+H_2 S_{(g)}\rightleftharpoons2HBr_{(g)}+\frac{1}{2}S_{2(s)}\) would have equilibrium constant
