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

question 36

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 these statements is true?

• A)The reaction is at equilibrium.
• B)The reaction will proceed in the direction of forming more PCl₅ until equilibrium is reached.
• C)The reaction will proceed in the direction of forming more PCl₃ and Cl₂ until equilibrium is reached.
• D)None of the above statements is true.
