Endothermic vs. Exothermic Reactions Extended Review

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat to its surroundings, causing the temperature of the surroundings to increase.

Front

What happens to the temperature of the surroundings during an exothermic reaction?

Back

The temperature of the surroundings increases.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings, causing the temperature of the surroundings to decrease.

What happens to the temperature of the surroundings during an endothermic reaction?

Back

The temperature of the surroundings decreases.

Front

What are reactants in a chemical equation?

Back

Reactants are the substances that undergo a chemical change in a reaction, found on the left side of a chemical equation.

Front

What are products in a chemical equation?

Back

Products are the substances that are formed as a result of a chemical reaction, found on the right side of a chemical equation.

Front

In an exothermic reaction, where does the energy go?

Back

In an exothermic reaction, energy is released into the surroundings.

Front

In an endothermic reaction, where does the energy come from?

Back

In an endothermic reaction, energy is absorbed from the surroundings.

Front

What is the role of energy in chemical reactions?

Back

Energy is required to break bonds in reactants and is released or absorbed when new bonds are formed in products.
