Endothermic vs. Exothermic Reactions + Bonds Breaking/Forming

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings.

Front

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

Back

The temperature of the surroundings decreases.

Front

What does the prefix 'endo' mean in the context of endothermic reactions?

Back

'Endo' means 'within'.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings.

Front

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

Back

The temperature of the surroundings increases.

Front

What is the relationship between bond breaking and energy?

Back

Breaking bonds requires energy.

Front

What is the relationship between bond formation and energy?

Back

Forming bonds releases energy.

Front

How can you identify an endothermic reaction based on temperature change?

Back

If the temperature decreases during a reaction, it is an endothermic reaction.

Front

How can you identify an exothermic reaction based on temperature change?

Back

If the temperature increases during a reaction, it is an exothermic reaction.

Front

What is the role of heat in endothermic reactions?

Back

Heat is absorbed from the surroundings to facilitate the reaction.
