Consider the following system at equilibrium where AH-108 kJ, and Ke=77.5, at 6.00 x 10² K
CO(g) + Cl₂(g) COCk₂ (9)
If the temperature on the equilibrium system is suddenly decreased:
The value of Ke
O increases
Odecreases
Oremains the same
The value of Q
O is less than Ke
Ois greater than Ke
Ois equal to Ke
The reaction must
Orun in the forward direction to reestablish equilibrium
Orun in the reverse direction to reestablish equilibrium
O remain in the current position, since it is already at equilibrium
The concentration of Cl₂ will
Oincrease
Odecrease
O remain the same

Temperature
Raising the temperature on an equilibrium system causes the system to try to absorb the added energy. Reducing the temperature causes the
system to try to restore the energy. You must, therefore, consider whether the reaction is endothermic or exothermic.

Endothermic Reactions
For an endothermic reaction, energy is absorbed when the reaction runs in the forward direction. You can think of energy as a reactant.
Reactants Energy Products
A
If the temperature is raised, the system responds by converting reactants to products and absorbing the added energy in the process. Similar to
when a reactant concentration increases, the system shifts toward products to consume the added energy. If the temperature is lowered, the
opposite happens.
The equilibrium constant increases when the temperature is raised on an endothermic reaction.
Exothermic Reactions
For an exothermic reaction, energy is absorbed when the reaction runs in the reverse direction. You can think of energy as a product.
Reactants Products + Energy
When the temperature is raised, the system responds by converting products to reactants and absorbing the added energy in the process.
Similar to when a product concentration increases, the system shifts toward reactants to consume the added energy. If the temperature is
lowered, the opposite happens.
The equilibrium constant decreases when the temperature is raised on an exothermic reaction.
Temperature is the only equilibrium variable that changes the value of the equilibrium constant.

LeChatelier's Principle:
A change in any of the factors that determine the equilibrium conditions of a system will cause the system to change in such
as to reduce or counteract the effect of the change.
Factors that determine the equilibrium conditions of a system are:
1. Concentration
2. Temperature (K changes)
3. Volume (Pressure) for gaseous systems.
