Question
Consider the following system at equilibrium where Delta H degree = -18.8 kJ, and Kc = 9.52E-2, at 350 K: CH4(g) + CCl4(g) 2 CH2Cl2(g) If the VOLUME of the equilibrium system is suddenly increased at constant temperature: The value of Kc Increases Decreases Remains the same The value of Q Is greater than K Is equal to K Is less than K The reaction must: Run in the forward direction to restablish equilibrium. Run in the reverse direction to restablish equilibrium. Remain the same. Already at equilibrium. The number of moles of CCl4 will: Increase. Decrease. Remain the same.Explanation / Answer
value of kc decreases
value of Q will less than K
the reaction will shift in forward direction
No. of CCl4 will decrease
