Why does a higher concentration increase the rate of reaction?

Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.

How does concentration affect the rate of reaction higher chemistry?

As the concentration of reactants increases, the rate of reactions also increases. If we squeeze more reacting particles into a smaller volume (increasing the concentration), then there is a greater chance that a collision will occur. More collisions means more reactions.

Why substances with high concentrations react faster than substances with low concentrations?

When the concentrations of the reactants are raised, the reaction proceeds more quickly. This is due to an increase in the number of molecules that have the minimum required energy. For gases, increasing pressure has the same effect as increasing concentration.

What makes a reaction occur faster?

Increasing the number of collisions speeds up the reaction rate. The more reactant molecules there are colliding, the faster the reaction will be. In most simple cases, increasing the concentration of the reactants increases the speed of the reaction.

How does the concentration of a catalyst affect a reaction?

Increasing the concentration of a reactant increases the frequency of collisions between reactants and will, therefore, increase the reaction rate. When a catalyst is added, the activation energy is lowered because the catalyst provides a new reaction pathway with lower activation energy.

What are everyday examples of concentration effects on reaction rate?

Increasing the concentration of reactants also changes reaction rate: Two antacid tablets will neutralize a given amount of acid faster than one tablet will. Higher concentrations of acid in rain erode marble faster than lower concentrations.

How does pH affect reaction rate?

pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature. Enzyme concentration: Increasing enzyme concentration will speed up the reaction, as long as there is substrate available to bind to.

What will disturb the equilibrium of a chemical reaction?

It is possible, however, to disturb that equilibrium by changing conditions. For example, you could increase the concentration of one of the products, or decrease the concentration of one of the reactants, or change the temperature.
