The pathophysiologies of diving diseases
The changes in ambient pressures when diving can cause pulmonary barotrauma. At high pressure, the increased tissue uptake of gases that are usually innocuous exposes a diver to their toxic effects, such as nitrogen narcosis and acute oxygen toxicity. Reduction in pressure during ascent may cause decompression sickness (DCS).

Explain why the nitrogen gas diffuses faster at the higher
The smaller the atomic pressure, the more prominent is the speed of the particles of gas. So as chlorine gas as a molar weight Cl2=71g and nitrogen a molar weight of N2 28g, it is normal that the atoms of chlorine diffuse more gradually than particles of nitrogen. Nitrogen is a substantial component of symbol N and nuclear number 7.
