Consider the oxidation of gold metal in a mixture of nitric and hydrochloric acids (aqua regia) to produce AuCl4^-(aq) while nitrate ion is reduced to NO(g).

Use 1/2 reactions to write a balanced redox equation for this oxidation of gold metal in this acid mixture to produce NO(g). Is this reaction spontaneous under standard conditions?
