Question

Consider the reaction Cl 2(g) + Br 2(g) <=> 2 BrCl(g), which is endothermic as written. What would be the effect on the equilibrium position of increasing the temperature? 1. Reaction would go to the right, making more "products" 2. Reaction would go to the left, making more "products" 3. Reaction would go to the left, making more "reactants" 4. Reaction would go to the right, making more "reactants" 5. No change on the equilibrium position

Answer 1

Hey there!:

endothermic reaction can be represented by   :

A + heat  B

So when  temperature is decreased , the system tries to oppose the change. SO it moves to the side where the temperature increases. I f it moves to product side, the temperature decreases as it it absorbing heat to form products.

 

So the system moves to the reactants side.

Answer 2

According to Le Châtelier's principle, an increase in temperature favors the endothermic process. Since the reaction, which proceeds towards bromine chloride, is endothermic, the reaction would shift right, making more products.
