Question

Consider the following reactions both occurring in the gaseous state:

1 2 NO₂ ↔ 2NO + O₂ ΔH = 114 kJ/mole

2 N₂ + 3 H₂ ---> 2 N H₃ ΔH = -92 kJ/mole

Le Chatelier's principle states that a system in equilibrium responds to a change imposed on the system in a way that minimizes the change imposed. Let's look at pressure, temperature and reactant/product changes and how the two reactions would respond assuming they are in sealed containers with some method to add gas(es).
