MDCAT Chemistry MCQ #2252

  1. Question 1

    Q1. A chemist calculates the reaction quotient Qc for a system and finds it is less than the equilibrium constant Kc. What is the predicted direction?

    • A) The reaction proceeds in the backward direction
    • B) The reaction proceeds in the forward direction
    • C) The reaction is already at equilibrium
    • D) The reaction stops and Kc becomes zero

    Answer: The reaction proceeds in the forward direction

    Explanation: If Qc < Kc, the reaction proceeds forward to reach equilibrium. Option A is wrong because it describes the reverse shift.
