What is the effect of increasing the concentration of a solution on the rate of reaction?

Back

Increasing the concentration of a solution increases the rate of reaction.

Front

Where does a chemical reaction occur in an experiment involving baking soda and vinegar?

Back

A chemical reaction occurs when baking soda and vinegar come into contact.

Front

How does the amount of hydrogen peroxide affect the foam produced in the elephant toothpaste experiment?

Back

More hydrogen peroxide increases the size and intensity of the foam.

Front

What factors affect the rate of reaction in the steel wool and oxygen experiment?

Back

Concentration and surface area affect the rate of reaction.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the role of temperature in chemical reactions?

Back

Increasing temperature generally increases the rate of reaction by providing more energy to the reactants.

Front

What is surface area and how does it affect reaction rates?

Back

Surface area refers to the exposed area of a reactant; greater surface area increases the rate of reaction.

Front

What is the effect of pressure on gas reactions?

Back

Increasing pressure increases the rate of reaction for gases by forcing the molecules closer together.

Front

What are inhibitors?

Back

Inhibitors are substances that decrease the rate of a chemical reaction.

Front

What is the collision theory?

Back

Collision theory states that for a reaction to occur, reactant particles must collide with sufficient energy and proper orientation.
