Problem

Consider a mixture of two gases, A and B, confined in a closed vessel. A quantity of a third gas, C, is added to the same vessel at the same temperature. How does the addition of gas C affect the following.

  • The partial pressure of gas A
Solution

We have to determine what would happen to the partial pressure of gas A when some quantity of gas C is added to a mixture of gases A and B.


Partial pressure is the pressure of a component in a gaseous mixture that it would exert if it were to occupy the entire volume alone.


We can use the ideal gas equation to calculate the partial pressure of a gas component using its moles, volume and temperature.

PV = nRT

Where,

P = pressure

V = volume

n = number of moles

R = gas constant = 0.08206 L•atm/mol•K

T = temperature in Kelvin units
