Use the References to access important values if needed for this question. Consider the following system at equilibrium where AHo -18.8 kJ/mol, and K. -9.52*101, at 350 K CH. (2 + CCL (2 CH,Ch (g) When 0.28 moles of CH, Ch (e) are added to the equilibrium system at constant temperature: The value of K The value of Qe The reaction must Orun in the forward direction to restablish equilibrium O run in the reverse direction to restablish equilibrium O remain the same. It is already at equilibrium The concentration of CC, wi Submit Answer

Explanation / Answer

A/C to Le Chatlier's principle, if we add any substance, the equilibrium will shift in a direction to decrease the amount of added substance.

Here we are adding CH2Cl2, so equilibrium shifts towards left side, reverse direction to decrease the amount of added CH2Cl2.

Hence Kc value decreases in reverse reaction

Qc value is greater than the Kc value.

Since Qc>Kc, reaction run in reverse direction

Concentration of CCl4 will increases.
