Endo and Exothermic Reactions

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 exothermic reaction?

Back

The temperature increases.

Front

What happens to temperature during an endothermic reaction?

Back

The temperature decreases.

Front

What is a catalyst?

Back

A catalyst is a substance that speeds up a chemical reaction without being consumed in the process.

Front

What is a chemical change?

Back

A chemical change is a process where substances combine or break apart to form new substances.

Front

What is a physical change?

Back

A physical change is a change that affects one or more physical properties of a substance without altering its chemical composition.

Front

What is the role of an inhibitor in a chemical reaction?

Back

An inhibitor is a substance that slows down or prevents a chemical reaction.

Front

What is the difference between endothermic and exothermic reactions?

Back

Endothermic reactions absorb heat, while exothermic reactions release heat.

Front

Give an example of an endothermic reaction.

Back

Photosynthesis is an example of an endothermic reaction, where plants absorb sunlight to convert carbon dioxide and water into glucose.
