Give the significance of critical point in the phase diagram of water.

Solid ammonium chloride undergoes sublimation on heating. In the vapour phase ammonium 

chloride decomposes to give NH3(g) and HCI(g). The following equilibrium is established.

What is the role of H2O in this reaction mechanism and what effect does it have on the overall reaction  rate? 

Ammonia NH3 gas and oxygen O2 gas react to form nitrogen N2 gas and water H2O vapor. Suppose you have 7.0 mol of NH3 and 9.0 mol of O2 in a reactor. Calculate the largest amount of N2 that could be produced. Round your answer to the nearest 0.1 mol.
