4. [25'] Consider the reaction 2NO₂ (g) → N₂O₂ (g) a) Calculate the value of AG at 298.15 K. b) Calculate the value of the equilibrium constant K at 298.15 K. c) Calculate the equilibrium pressure of a system that initially consists of 1.0 mol of dinitrogen tetraoxide and is confined in a fixed volume of 24.46 L at 298.15K. The standard Gibbs free energies of formation are: for NO2, AG = +51.31 kJ mol¹¹, for N₂04, AG° = +97.89 kJ mol™¹.
