MDCAT Chemistry MCQ #2227

  1. Question 1

    Q1. During the industrial production of SO3, a technician calculates that the reaction quotient (Qc) is 1.5 while Kc is 2.5. This indicates that:

    • A) The reaction proceeds in the reverse direction
    • B) The reaction proceeds in the forward direction
    • C) The system has already reached equilibrium
    • D) The value of Kc will increase to match Qc

    Answer: The reaction proceeds in the forward direction

    Explanation: When Qc is less than Kc, the system must produce more products to reach equilibrium, unlike Qc > Kc which shifts backward.
