Question

Consider the following system at equilibrium where AHo 108 kJ, and Ke 77.5, at 600 K CO(g) + ChgCOC2(g) If the VOLUME of the equilibrium system is suddenly decreased at constant temperature The value of KeA increa A. increases B. decreases C. remains the same A. ?sgreater than Kc B. is equal to Ke C is less than Kc The value of C A run in the forward direction to reestablish equilibrium. B. run in the reverse direction to reestablish equilibrium. The reaction must: remain the same. It is already at equilibrium A. increase B. decrease C remain the same The number of moles of CI Retry Entire Groug

Explanation / Answer

If the VOLUME of the equilibrium system is suddenly decreased at constant temperature

The value of Kc   remains the same because Kc depends only affected by temperature ( Here temperature is constatnt)

The value of Qc is less than Kc ( Higher Kc means product favor wheres as lower Kc value Qc is favor )

The reaction must run in the forward direction to reestablish equilibrium because of higher Kc value ( more than 1)

The number of moles of Cl2 will decrease.
