A mixture of N₂O₄(g) and NO₂(g) is contained in a vessel whose total volume can change but where the total pressure is maintained at 1.00 atm. The initial temperature is 298 K, and the two gases are in equilibrium. Which changes will result in an increase in the number of moles of NO₂ present at equilibrium?
N₂O₄(g) ⇌ 2 NO₂(g) ∆H° = 57.6 kJ mol^-1
I. Adding Ne(g)
II. Increasing the temperature to 310 K
