What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat, resulting in an increase in the temperature of the surroundings.

Front

Do the reactants in an exothermic reaction have a higher or lower energy than the products?

Back

Higher

Front

What is the enthalpy change (ΔH) in an exothermic reaction?

Back

The enthalpy change (ΔH) is negative, indicating that energy is released.

Front

Which statement is true regarding exothermic reactions?

Back

Temperature change is positive and enthalpy change is negative.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings, resulting in a decrease in the temperature of the surroundings.

Front

Do the reactants in an endothermic reaction have a higher or lower energy than the products?

Back

Lower

Front

What is the enthalpy change (ΔH) in an endothermic reaction?

Back

The enthalpy change (ΔH) is positive, indicating that energy is absorbed.

Front

What does a positive temperature change indicate in a reaction?

Back

A positive temperature change indicates that the reaction is exothermic.

Front

What does a negative temperature change indicate in a reaction?

Back

A negative temperature change indicates that the reaction is endothermic.
