Activation Energy

Front

What is Activation Energy?

Back

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

Front

What is an Endothermic Process?

Back

An Endothermic Process is a reaction that absorbs energy from its surroundings, resulting in a decrease in temperature.

Front

What is an Exothermic Process?

Back

An Exothermic Process is a reaction that releases energy to its surroundings, resulting in an increase in temperature.

Front

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

Back

The temperature of the surroundings increases.

Front

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

Back

The temperature of the surroundings decreases.

Front

Give an example of an Endothermic reaction.

Back

Baking bread is an example of an Endothermic reaction.

Front

Give an example of an Exothermic reaction.

Back

Water freezing to form ice is an example of an Exothermic reaction.

Front

What is the relationship between Activation Energy and reaction rate?

Back

Higher Activation Energy generally means a slower reaction rate, while lower Activation Energy means a faster reaction rate.

Front

What is the role of catalysts in chemical reactions?

Back

Catalysts lower the Activation Energy required for a reaction, increasing the reaction rate without being consumed.

Front

What is the significance of the term 'system' in thermodynamics?

Back

The 'system' refers to the part of the universe being studied, while the 'surroundings' are everything outside the system.
