Calculate AG for the reaction given below if the partial pressure of NO₂ is 0.220 atm and the partial pressure of N₂O4 is 0.428 atm. 2NO2(g) = N₂O4(8) AG 298 of this reaction is -5.40 kJ per mole of N₂O. T = 298K, R = 8.314 J.mol-¹.K-1 Note: Round you answer to 2 decimal places. AG = i kJ mol-1 Where does the system stand relative to equilibrium? O The system is at equilibrium, so that the reaction will not move. O The equilibrium shifts to products. O The equilibrium shifts to reactants.

Nitrogen dioxide is produced by reacting nitric oxide and oxygen: 2NO(g) + 02(g) $2NO2(g) ; AH° = -114 kJ Under which reaction conditions would you expect to have the greatest equilibrium yield of nitric oxide? O high temperature, high pressure O low temperature, high pressure O high temperature, low pressure O low temperature, low pressure

Consider the reaction: N2(g) + 3 F2(g) –→ 2 NF3(g) AH° = -249 kJ and AS° = -278 J/K at 25°C Calculate AG° and state whether the reaction is reactant favored or product favored at standard conditions. AG° = -166 kJ; the equilibrium composition should favor reactants. AG° = -332 kJ; the equilibrium composition should favor reactants. AG° = -332 kJ; the equilibrium composition should favor products. None of these AG° = -166 kJ; the equilibrium composition should favor products.
