question 28

Multiple Choice

Consider the following equilibrium: C₂H₆(g) + C₅H₁₂(g) CH₄(g) + C₆H₁₄(g) ; K_p = 9.57 at 500 K
Suppose 22.7 g each of CH₄,C₂H₆,C₅H₁₂,and C₆H₁₄ are placed in a 35.0-L reaction vessel at 500 K.Which of the following statements is correct?

• A) Because Q_c < K_c,more products will be formed.
• B) Because Q_c = 1,the system is at equilibrium.
• C) Because Q_c = 1,more products will be formed.
• D) Because Q_c = 1,more reactants will be formed.
• E) Because Q_c > K_c,more reactants will be formed.
