If a mixture of CO and N₂ in equal amount have total 1 atm pressure, then partial pressure of N₂ in the mixture is

Options

(a) 1 atm
(b) 0.50 atm
(c) 2 atm
(d) 3 atm

Correct Answer:

0.50 atm

Explanation:

Partial pressure of a component = Mole fraction × Total pressure
pɴ₂ = (Number of moles of N₂ / Total number of moles) × 1
pɴ₂ = (1 / 2) × 1 = 0.5 atm
