Question
Consider the following system at equilibrium where H°-108 kJ, and K.-1.29x10-2, at 600 K: CoC2(g) COg)+C2(g) If the TEMPERATURE on the equilibrium system is suddenly increased: The value of KcA. Increases B. Decreases C. Remains the same The value of Qc A. Is greater than Kc B. Is equal to Kc C. Is less than Kc The reaction must:A. Run in the forward direction to restablish equilibrium. B. Run in the reverse direction to restablish equilibrium C. Remain the same. Already at equilibrium The concentration of Ch will:A. Increase B. Decrease C. Remain the same.Explanation / Answer
1)the value of kc will change as it is an endothermic reaction the increase in temperature increases the kc value
2)Qc is less than kc 3)runs in forward direction 4) concentration of cl2 will increase as reaction proceeds towards forward direction
