The partial pressures of Argon and Nitrogen in the atmosphere are 0.0093 (93*10-4 atm) and 0.8 (0.8 atm) at sea level, respectively. At which altitudes the concentrations of these gases will be half of the corresponding sea level ones? Compare results and comment.
Assume that T= 20 oC and that does not change with altitude (not true).
g = 9.807 m/s2; T = 293 K;
R = 8.32 J/K mol;
The molecular weights of Ar and N2 are 39.9 g/mol and 24 g/mol, respectively.
