What is homogeneous equilibrium? Give examples.

(N/A) Definition: In a homogeneous system,all the reactants and products are in the same phase.
Example $1$: $A$ reaction where all species are in the gaseous phase:
$N_{2(g)} + 3H_{2(g)} \rightleftharpoons 2NH_{3(g)}$
Example $2$: $A$ reaction where all reactants and products are in the aqueous solution phase:
$Fe^{3+}_{(aq)} + SCN^{-}_{(aq)} \rightleftharpoons [Fe(SCN)]^{2+}_{(aq)}$
