Multiple choice

If a mixture of CO and N2, in equal amount, has a total pressure of 1 atm, find out the partial pressure of N2 in a mixture.

  1. 1 atm

  2. 0.50 atm

  3. 2 atm

  4. 3 atm

B Correct answer
Explanation

In a mixture of gases, the partial pressure is proportional to the mole fraction. Since the amounts of CO and N2 are equal, their mole fractions are both 0.5. Thus, the partial pressure of N2 is 0.5 * 1 atm = 0.5 atm.

AI explanation

According to Dalton's law of partial pressures, the partial pressure of a gas in a mixture is equal to its mole fraction multiplied by the total pressure. Since the mixture contains equal amounts of carbon monoxide and nitrogen, the mole fraction of nitrogen is 0.5. Multiplying this mole fraction by the total pressure of 1 atm gives a partial pressure of 0.50 atm for nitrogen.
