Chemistry - Chemical Equilibrium Question with Solution | TestHub

$\mathrm{N}{\mathrm{H}}_3$is presenting on product side. Hence on adding$\mathrm{N}{\mathrm{H}}_3$, equilibrium shift to backward thus concentration of$\left[\mathrm{C}\mathrm{u}{\left(\mathrm{N}{\mathrm{H}}_3\right)}_3\mathrm{S}{\mathrm{O}}_3\right]$would decrease.
