For the reaction, 2SO2(g) + O2(g) �¨ 2SO3(g) + heat, at equilibrium, what will be the effect on the net amount of SO3 present if the temperature of the container is increased?

A) The concentration of SO3 decreases.

B) The concentration of SO3 increases.

C) The concentration of SO3 remains the same.

D) This question cannot be answered without knowing the value of Keq.

any help will be greatly appreciated. Thank You So Much!!!

The effect of temperature on the net amount of SO3 present in the equilibrium reaction 2SO2(g) + O2(g) → 2SO3(g) + heat can be determined by looking at the reaction's equilibrium constant, Keq.

In general, an increase in temperature will favor the endothermic direction of the reaction (the side with "heat" in the equation) and decrease the net amount of products. Conversely, a decrease in temperature will favor the exothermic direction of the reaction and increase the net amount of products.

Since the reaction is exothermic (heat is a product), an increase in temperature will shift the equilibrium position to the left, reducing the net amount of SO3 present. Therefore, the correct answer is:

A) The concentration of SO3 decreases.

To determine the effect of an increase in temperature on the net amount of SO3 present in the reaction, we need to consider the principle known as Le Chatelier's principle.

Le Chatelier's principle states that when a system at equilibrium is subjected to a change, it will adjust in a way that counteracts the change to maintain equilibrium. In this case, an increase in temperature is causing a disturbance to the system at equilibrium.

In the given reaction, the formation of SO3 is exothermic, meaning it releases heat. According to Le Chatelier's principle, if the temperature is increased, the system will shift in the direction that absorbs heat, which is the backward reaction.

Therefore, an increase in temperature will cause the reaction to favor the reverse reaction (2SO3(g) �+ O2(g) �¨ 2SO2(g) + heat), resulting in a decrease in the net amount of SO3 present.

Based on this analysis, the correct answer would be:

A) The concentration of SO3 decreases.

Increasing T will make the reaction shift to the left; therefore, the amount of SO3 will decrease. BUT you need to be able to do these by yourself. What is confusing you about Le Chatelier's Principle?
