A cylinder is filled with a gaseous mixture containing equal masses of CO and N2. The partial pressure ratio is : (a) N CO P P (b) CO N P 0.875 P (c) CO N P 2 P (d) CO N P 1/ 2 P
Answer
A
Explanation
Given- 2 Weight( ) Weight( ) CO N We know that Partial Pressure= Mole fraction Total Pressure x Also, Molecular weight of both the gases are equal 2 2 1 Mole Fraction of and N 2 CO 2 2 2 12 1 12 N N CO CO N CO P X P P X P P P x x >>
