In an endothermic reaction at equilibrium, what is the effect of raising the temperature?
The reaction makes more products
the reaction makes more reactants***
the reaction is unchanged
the answer cannot be determined
To determine the effect of raising the temperature on an endothermic reaction at equilibrium, we need to understand Le Chatelier's principle. According to this principle, when a system at equilibrium is subjected to a change in conditions, it will respond in such a way as to minimize the effect of that change.
In the case of an endothermic reaction, increasing the temperature is equivalent to providing heat to the system. This change in temperature disrupts the equilibrium, and the reaction responds by shifting in the direction that absorbs more heat, which is the endothermic direction.
Therefore, if the reaction is endothermic and we raise the temperature, the system will shift in the direction that consumes heat. This means that more reactants will be converted into products in order to absorb the additional heat, resulting in an increase in product formation.
So, in response to the question, the correct answer is "the reaction makes more products."
