Endothermic and Exothermic Reactions

Front

What is kinetic energy in the context of chemical reactions?

Back

Energy associated with motion.

Front

What best describes an exothermic reaction?

Back

A reaction that releases stored energy.

Front

What is a characteristic of an exothermic reaction?

Back

The reaction releases energy, often as heat or light.

Front

What is the main difference between endothermic and exothermic reactions in terms of energy?

Back

Endothermic reactions absorb energy, while exothermic reactions release energy.

Front

What happens to the energy in the reactants during an exothermic reaction?

Back

It is released as thermal energy.

Front

Define an endothermic reaction.

Back

A reaction that absorbs energy from its surroundings.

Front

What is an example of an endothermic reaction?

Back

Photosynthesis, where plants absorb sunlight.

Front

What is an example of an exothermic reaction?

Back

Combustion of fuels, such as burning wood.

Front

How do temperature changes relate to exothermic reactions?

Back

Exothermic reactions typically result in an increase in temperature.

Front

How do temperature changes relate to endothermic reactions?

Back

Endothermic reactions typically result in a decrease in temperature.
