PD1- MRMS MP2: 2025: Exothermic/Endothermic Flashcard

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 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 happens to temperature during an exothermic reaction?

Back

The temperature increases.

Front

What happens to temperature during an endothermic reaction?

Back

The temperature decreases.

Front

Give an example of an exothermic reaction.

Back

Combustion of fuels, such as burning wood or gasoline.

Front

Give an example of an endothermic reaction.

Back

Photosynthesis in plants, where they absorb sunlight.

Front

What is the role of heat in an endothermic reaction?

Back

Heat is taken in or absorbed from the surroundings.

Front

What is the role of heat in an exothermic reaction?

Back

Heat is given out or released to the surroundings.

Front

How can you identify an exothermic reaction from a graph?

Back

The graph will show a decrease in energy of the system as heat is released.

Front

How can you identify an endothermic reaction from a graph?

Back

The graph will show an increase in energy of the system as heat is absorbed.
