Rev Use the References to nccezs important valnes if needed for thiz queation. -9.52x102 , at 350 K: Consider the following system at equilibrium where ??. 18.8 kl, and K CH4 (g) + CCl4 (g) 2 CH2C12 (g) If the TEMPERATURE on the equilibrium system is suddenly increased The value of KeA Increases B: Decreases C Remains the same The value of QeA ls greater than Ke B Is equat to Ke C Is less than Ke The reaction must ARea in the fhaward directon to restablish equdibi B Run in the reverse direction to restablish equilibrium Remain the samel Atready at equilibrium The concentration of CCiq will: A. Increase B. Decrease C Remain the same

Explanation / Answer

From the Le chatelier's principle

The reaction is endothermic because H is positive

Increase in temperature favors to forward side of the reaction .

Equilibrium constant expression

Kc will increase

Qc < Kc

The reaction must run in the forward reaction

Moles of CCl4 decrease
