${\mathrm{Fe}}_{\left(\mathrm{aq}\right)}^{+3}+{\mathrm{SCN}}_{\left(\mathrm{aq}\right)}^{ }\rightleftharpoons {\left[\mathrm{Fe} {\left(\mathrm{SCN}\right)}_{\left(\mathrm{aq}\right)}^{ }\right]}^{+2}$ is an example of 

${\mathrm{Fe}}_{\left(\mathrm{aq}\right)}^{+3}+{\mathrm{SCN}}_{\left(\mathrm{aq}\right)}^{ }\rightleftharpoons {\left[\mathrm{Fe} {\left(\mathrm{SCN}\right)}_{\left(\mathrm{aq}\right)}^{ }\right]}^{+2}$ in equilibrium reaction all reactants and products are in same phase, hence this equilibrium reaction is called homogenous equilibrium reaction
