Endothermic Vs 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

In an endothermic reaction, is energy absorbed or released?

Back

Energy is absorbed in an endothermic reaction.

Front

In an exothermic reaction, is energy absorbed or released?

Back

Energy is released in an exothermic reaction.

Front

What happens to the temperature of the surroundings in an exothermic reaction?

Back

The temperature of the surroundings increases in an exothermic reaction.

Front

What happens to the temperature of the surroundings in an endothermic reaction?

Back

The temperature of the surroundings decreases in an endothermic reaction.

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.

Front

Give an example of an exothermic reaction.

Back

Combustion of fuels, such as burning wood or gasoline, is an example of an exothermic reaction.

Front

What is the role of activation energy in chemical reactions?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How can you identify an exothermic reaction from a temperature change?

Back

If the temperature of the reaction mixture increases, it indicates an exothermic reaction.
