Nitrogen gas has a henrys law constant k 6.3 times 10-4, Ask an Expert

Academics

Nitrogen gas has a Henry's law constant k = 6.3 × 10-4 M/atm at 25°C. The "bends" in divers results from bubbles of N2(g) being rapidly released from body fluids when a diver ascends to the surface too quickly. Which of the following would be a good substitute for N2(g) in order to make the "bends" less severe?

a. He(g), k = 3.7 × 10-4 M/atm

b. Ar(g), k = 1.5 × 10-3 M/atm

c. H2(g), k = 8.1 × 10-4 M/atm

d. CO2(g), k = 3.4 × 10-2 M/atm

e. All of the above
