Reaction Rates

Front

What are the five factors that can affect reaction rate?

Back

Temperature, Concentration, Surface Area, Pressure, Catalysts

Front

What is the energy released when making bonds called?

Back

Exothermic Energy

Front

What happens to the reaction rate if you add more reactants to a reaction?

Back

It will speed up.

Front

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

Back

Agitation/Stirring

Front

Which factor increases reaction rates by causing particles to move faster?

Back

Increase in Pressure of gases.

Front

Define Activation Energy.

Back

The minimum energy required for a chemical reaction to occur.

Front

What is the effect of increasing temperature on reaction rates?

Back

It generally increases the reaction rate.

Front

How does surface area affect reaction rates?

Back

Increased surface area allows more collisions, thus increasing the reaction rate.

Front

What role do catalysts play in chemical reactions?

Back

They speed up the reaction without being consumed in the process.

Front

What is the difference between exothermic and endothermic reactions?

Back

Exothermic reactions release energy, while endothermic reactions absorb energy.
