Answer:
C. Remains the same
A. Is greater than Kc
B. Run in the reverse direction to restablish equilibrium.
C. Remain the same
Explanation:
As the reaction is exothermic (ΔH < 0), when occurs, produce heat.
Based on Le Chatelier's principle, if the temperature decreases, <em>the system will produce more product trying to restore the equilibrium</em>
* The value of Kc doesn't change because is the constant of the reaction, Kc. That is,
<h3>C. Remains the same</h3>
* Qc is the ratio between products and reactants. As more product is produced, Qc will increase becomes:
<h3>A. Is greater than Kc</h3>
*After the formation of product, the system must:
<h3>B. Run in the reverse direction to restablish equilibrium. </h3>
Because product is produced
*Cl₂ as reactant is consumed producing more product, decreasing its concentration. But when the equilibrium is restored, its concentration would be the same
<h3>C. Remain the same</h3>
