How does the concentration of the reactants affect the amount of product obtained? In general, does an increased concentration of reactant give more product? What are the exceptions?

Does it matter if it's exothermic or endothermic? If the reactants/products are in liquid/aqueous state? Anything else that might affect whether the concentration affects the amount of product obtained?

Any help is greatly appreciated. Any other information regarding concentration in Le Chatelier's Principle would also be extremely helpful! Thanks a lot.

By your question, it is evident you missed the point of Le Chatelier: Reaction dynamics tend to undo a reaction in equilibrium if a reaction condition (temp, pressure, concentration) has been altered.

This article explains it well, somewhat wordy, but well:

The concentration of reactants can indeed affect the amount of product obtained in a chemical reaction. In general, increasing the concentration of reactants will increase the rate of the reaction, which can often lead to an increased amount of product formed. This is because an increase in concentration provides more reactant molecules, leading to more frequent collisions between reactant particles and an increased likelihood of successful collisions.

However, there are some exceptions to this general rule. One exception is when the reaction is already at or near completion, meaning most of the reactants have already been converted into products. In this case, increasing the concentration of reactants will not have a significant impact on the amount of product obtained. Additionally, some reactions may exhibit a limiting reactant, which means that the reaction will only proceed until the point where the limiting reactant is completely consumed. In these cases, increasing the concentration of the other reactants will not result in more product.

The effect of concentration on the amount of product obtained can also depend on other factors such as the nature of the reaction. For example, exothermic reactions release heat, and an increase in concentration could potentially increase the reaction rate by providing more energy for the reaction to proceed. On the other hand, endothermic reactions absorb heat, and an increase in concentration might not have the same significant effect on the reaction rate.

The physical state of the reactants and products can also impact the effect of concentration. In a liquid or aqueous state, increasing the concentration increases the number of particles per unit volume, resulting in a higher collision frequency and potentially leading to a higher reaction rate. However, in a gaseous state, the volume and pressure can also play a role, as changes in pressure can affect the equilibrium position of the reaction.

Le Chatelier's Principle is a concept that relates to the effect of various factors on the equilibrium position of a reaction. Concentration changes, as well as changes in temperature and pressure, can all affect the equilibrium of a chemical reaction. According to Le Chatelier's Principle, if the concentration of one of the reactants is increased, the system will try to counteract the change by shifting the reaction towards the products or the reactants, depending on the specific reaction. Similarly, if the concentration of a product is increased, the system will try to reduce the excess by shifting the reaction towards the reactants. This principle helps us understand how a change in concentration can influence the equilibrium and ultimately affect the amount of product obtained.

I hope this information helps. Do let me know if you have any further questions!
