Reaction Rates

Front

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

Back

The reaction rate will speed up.

Front

What is the energy released when making bonds called?

Back

Exothermic Energy.

Front

Which process absorbs energy and feels cool to the observer?

Back

Endothermic process.

Front

List the five factors that can affect reaction rate.

Back

Temperature, Concentration, Surface Area, Pressure, Catalysts.

Front

What effect does a catalyst have on the activation energy of a reaction?

Back

It decreases the activation energy.

Front

Define reaction rate.

Back

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

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

What is an exothermic reaction?

Back

A reaction that releases energy, usually in the form of heat.

Front

What is an endothermic reaction?

Back

A reaction that absorbs energy from its surroundings.

Front

How does temperature affect reaction rates?

Back

Increasing temperature generally increases reaction rates.
