A container has gas mixture of 40% CO2 and 60% H2 with total pressure 10 Pa, if now O2 is added to it isothermally so that the final composition of the mixture becomes 20% CO2, 30% H2, and 50% O2, what is the partial pressure of O2 in the new composition?(a) 5 Pa(b) 10 Pa(c) 20 Pa(d) 35 Pa

A container has gas mixture of 40% CO2 and 60% H2 with total pressure

1.	A container has gas mixture of 40% CO2 and 60% H2 with total pressure 10 Pa, if now O2 is added to it isothermally so that the final composition of the mixture becomes 20% CO2, 30% H2, and 50% O2, what is the partial pressure of O2 in the new composition?(a) 5 Pa(b) 10 Pa(c) 20 Pa(d) 35 Pa
Answer» The correct choice is (b) 10 Pa For explanation: Partial pressure of H2 = 0.610 = 6 Pa, => Partial pressure of O2 = 0.56/0.3 = 10 Pa.
