MDCAT Chemistry MCQ #2221

  1. Question 1

    Q1. In a Haber process mixture at 12 atm, there are 1 mole of N2, 3 moles of H2, and 2 moles of NH3. Calculate the partial pressure of NH3.

    • A) 4 atm
    • B) 6 atm
    • C) 2 atm
    • D) 8 atm

    Answer: 4 atm

    Explanation: Partial pressure = mole fraction × total pressure. Total moles = 1+3+2 = 6. P(NH3) = (2/6) × 12 atm = 4 atm. Option B incorrectly uses the mole ratio 2/4.
