PD3 - MRMS MP2: 2025: Exothermic/Endothermic Flashcard

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, resulting in a decrease in temperature.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings, resulting in an increase in temperature.

Front

What happens to temperature during an endothermic reaction?

Back

The temperature of the surroundings decreases.

Front

What happens to temperature during an exothermic reaction?

Back

The temperature of the surroundings increases.

Front

Give an example of an endothermic process.

Back

Evaporation of water is an endothermic process because it absorbs heat.

Front

Give an example of an exothermic process.

Back

Combustion of fuels, such as burning wood or fireworks exploding, is an exothermic process.

Front

What is the role of heat in an endothermic reaction?

Back

Heat is absorbed from the surroundings to drive the reaction.

Front

What is the role of heat in an exothermic reaction?

Back

Heat is released into the surroundings as a product of the reaction.

Front

How can you identify an exothermic reaction on a graph?

Back

An exothermic reaction will show a decrease in energy over time, indicating that energy is being released.

Front

How can you identify an endothermic reaction on a graph?

Back

An endothermic reaction will show an increase in energy over time, indicating that energy is being absorbed.
