You are searching for the IIT JEE Part I: Chemistry question papers. Here I am providing you the IIT JEE Part I: Chemistry some sample question. That is as follows.


The Henry’s law constant for the solubility of N2 gas in water at 298 K is 1.0 × 105 atm. The mole fraction
of N2 in air is 0.8. The number of moles of N2 from air dissolved in 10 moles of water at 298 K and 5 atm
pressure is
(A) 4.0 × 10−4 (B) 4.0 × 10−5
(C) 5.0 × 10−4 (D) 4.0 × 10−6
Sol. (A)
P = KH 2 N χ
0.8 × 5 = 1 × 105 × 2 N χ
2 N χ = 4 × 10-5 (in 10 moles of water)
