Solution

The correct option is B $5 : 1$
A 5-mole sample of oxygen gas is added to a vessel that contains 1
mole of hydrogen gas and that is maintained at a constant temperature. No chemical reaction occurs. The volume of the vessel remains unchanged.
The ratio of the pressure exerted by the oxygen gas to the pressure exerted by the hydrogen gas is 5:1. It is same as the ratio of the number of moles of oxygen gas to the number of moles of hydrogen gas. It is same as the mole fraction of oxygen gas to the mole fraction of hydrogen gas.
Note: The partial pressure of a gas is directly proportional to its mole fraction.
