Reaction Rates

Front

What is the main factor that increases reaction rates by causing particles to move faster?

Back

Increase in Pressure of gases.

Front

How does increasing the surface area of a reactant affect the rate of a chemical reaction?

Back

It increases the rate of reaction.

Front

What happens to the reaction rate when more reactants are added to a reaction?

Back

It will speed up.

Front

List the five factors that can affect reaction rate.

Back

Temperature, Concentration, Surface Area, Pressure, Catalysts.

Front

Which factor increases reaction rates by causing more particles and more collisions?

Back

Agitation/Stirring.

Front

Define reaction rate.

Back

The speed at which reactants are converted into products in a chemical reaction.

Front

What role do catalysts play in chemical reactions?

Back

They increase the reaction rate without being consumed in the process.

Front

How does temperature affect reaction rates?

Back

Increasing temperature generally increases reaction rates by providing more energy to the particles.

Front

What is the effect of concentration on reaction rates?

Back

Higher concentration of reactants typically leads to an increased reaction rate.

Front

Explain how pressure affects the reaction rates of gases.

Back

Increasing pressure forces gas particles closer together, leading to more frequent collisions and a higher reaction rate.
