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 temperature decrease.

Front

What is an exothermic reaction?

Back

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

Front

What is a sign that a chemical reaction has occurred?

Back

Signs of a chemical reaction include the production of gas (bubbles), color change, temperature change, and formation of a precipitate.

Front

What role does a catalyst play in a chemical reaction?

Back

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

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 exothermic reaction.

Back

Burning a match is an example of an exothermic reaction.

Front

What happens to the temperature during an endothermic reaction?

Back

The temperature decreases as heat is absorbed from the surroundings.

Front

What happens to the temperature during an exothermic reaction?

Back

The temperature increases as heat is released to the surroundings.

Front

What is a common sign of an exothermic reaction?

Back

A common sign of an exothermic reaction is an increase in temperature.

Front

What is a common sign of an endothermic reaction?

Back

A common sign of an endothermic reaction is a decrease in temperature.
