For the Reaction PCl₃(g)+ Cl₂(g) PCl₅(g)at a Particular

question 1

Multiple Choice

For the reaction PCl₃(g) + Cl₂(g) PCl₅(g) at a particular temperature, K_c = 24.3.Suppose a system at that temperature is prepared with [PCl₃] = 0.10 M, [Cl₂] = 0.15 M, and [PCl₅] = 0.60 M.Which of the following is true based on the above?

• A)Q_c > K_c, the reaction proceeds from left to right to reach equilibrium
• B)Q_c > K_c, the reaction proceeds from right to left to reach equilibrium
• C)Q_c < K_c, the reaction proceeds from left to right to reach equilibrium
• D)Q_c < K_c, the reaction proceeds from right to left to reach equilibrium
• E)Q_c = K_c, the reaction is currently at equilibrium
