Front

What is the effect of decreasing particle size on the rate of reaction?

Back

Increasing the rate of reaction.

Front

What type of reaction is characterized by the release of energy?

Back

Exothermic reaction.

Front

What does 'B' represent in a reaction energy diagram?

Back

Activation Energy.

Front

Which factor affecting reaction rate is represented by surface area?

Back

Surface Area increases the rate of reaction.

Front

What is the effect of increasing temperature on the rate of reaction?

Back

Increasing the rate of reaction.

Front

Define reaction rate.

Back

The speed at which reactants are converted into products.

Front

What is activation energy?

Back

The minimum energy required for a reaction to occur.

Front

How does concentration affect reaction rate?

Back

Increasing concentration increases the rate of reaction.

Front

What is a catalyst?

Back

A substance that increases the rate of a reaction without being consumed.

Front

What is the difference between endothermic and exothermic reactions?

Back

Endothermic reactions absorb energy; exothermic reactions release energy.
