Question

Which best defines partial pressure in a mixture of gases? pressure that is exerted by all the gases of a mixture on the container pressure that is exerted by one gas as if it occupied a container by itself half of the pressure that is exerted by the gases of a mixture on the container sum of the individual pressures that are exerted by two or more gases

Answer 1

The best definition is pressure that is exerted by one gas as if it occupied a container by itself. Thepartial pressure of one gas in amixture of gases, contained in a given volume, is the pressure thatone gas would exert if it occupiedthe entire volume all byitself.

Answer 2

Correct answer is the fourth option- "Sum of the individual pressures that are exerted by two or more gases."

According to Dalton's law of partial pressure, the total pressure of the mixture of gases will be always equal to the sum of the partial pressures exerted by the individual gases present in the gaseous mixture.

Partial pressure of gaseous mixture = Partial pressure of a gas 1 + Partial pressure of a gas 2 +......+ Partial pressure of a gas 'n'.

Hope it helps. Thank You!
