Use the References to access important values if needed for this question Consider the following system at equilibrium where h": 10S ki, and K.-129-102, at 600 K. If the TEMPERATURE on the equilibrium system is suddenly decreased The value of Kc bA. Increases B. Decreases C. Remains the same The value of Qc aA. Is greater than K B. Is equal to K C. Is less than K The reaction mst: a A. Run in the forward direction to restablish equilbrium B. Run in the reverse direction to restablish equilbnum C. Remain the same. Already at equilibrium. The concentration of Cl, will: A Increase. B. Decrease C. Remain the same 9 more group attempts remaiming Retry Entire Group ed

Explanation / Answer

The reaction is endothermic as it has positive enthalpy for the reaction.

When the temperature is decreased , the reaction tends to move in the reverse direction , i.e in the direction of reactants.

So according to the Le Chatelier's Principle :

The value of Kc B, i.e. decreases

The value of Qc A, is greater than Kc

The reaction must A , must run in the forward direction to reestabilish the equillibrium

The concentration of Cl2 will B decrease
