Can someone help me with my AP Chem quiz on thermodynamics? Answer questions about the theoretical reactions given:.

Reaction 1: A2 (g) + B2 (g) ⇄ 2 AB (g) ΔHrx = 20 kJ/mole ΔS0298 = 80 J/mole K

(a) Is this reaction thermodynamically favored (spontaneous) under standard conditions? Justify your answer with a calculation. (Find ΔG0)

(b) Determine the value of the equilibrium constant (Keq) for this reaction at 298 K

(c) If 1 mole of A2, 1 mole of B2, and 1 mole of AB are all placed into a 1 L container at standard conditions, what will happen (increase, decrease, nothing) to the moles of AB in the container? Justify your answer.
