Question
A vessel of volume 2.0 dm³ containing gas A at a pressure of
100 kPa is connected by a tap to another vessel of volume
3.0 dm3 containing gas B at 300 kPa. When the tap are
opened, the two gases mixed thoroughly. If the temperature
is kept constant and the gas behave ideally, calculate
(a) the partial pressures of gases A and B
(b) the final pressure in the vessels
(c) the mole fractions of A and B
Ans: PA = 40 kPa, Pg = 180 kPa, P7 = 220 kPa, Xa = 0.18, Xg = 0.82
