A typical recreational scuba diver might fill his or her breathing tank with a mixture of nitrogen (P =136 atm) and oxygen (P = 64 atm). Below is an equilibrium that exists between oxygen and
nitrogen gases at 298 K:
N2(g) + O2(g) + 2NO(g); K = 4.1x 10-31.Nitrogen monoxide is a pretty nasty gas that will burn the lungs when inhaled in high enough concentrations. Should the diver be concerned about the toxic gas?
