Reaction Rates

Front

What is the effect of higher concentration on reaction rates?

Back

Higher concentration increases the frequency of particle collisions because there are more collision sites.

Front

How does temperature affect the rate of a chemical reaction?

Back

Higher temperature increases both the frequency and energy of particle collisions.

Front

What can be done to slow down a chemical reaction?

Back

Placing the reactants in an ice bath can slow down a chemical reaction.

Front

What happens to the rate of product formation when reactant concentration increases?

Back

Products will form faster if the concentration of the reactants is increased.

Front

How does the rate of a chemical reaction change with reactant concentration?

Back

The rate of a chemical reaction normally increases as reactant concentration increases.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What role do catalysts play in chemical reactions?

Back

Catalysts increase the rate of a reaction by lowering the activation energy.

Front

How does particle size affect reaction rates?

Back

Smaller particle size increases the surface area, leading to more frequent collisions and a faster reaction rate.

Front

What is the relationship between reaction rate and temperature?

Back

Generally, as temperature increases, the reaction rate increases due to more energetic collisions.

Front

What is the effect of stirring on reaction rates?

Back

Stirring can increase the reaction rate by distributing reactants more evenly and increasing collision frequency.
