Endothermic and Exothermic Assessment

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 the temperature during an endothermic reaction?

Back

The temperature decreases because the reaction absorbs heat.

Front

What happens to the temperature during an exothermic reaction?

Back

The temperature increases because the reaction releases heat.

Front

In an endothermic reaction, do the reactants or products have higher energy?

Back

The products have higher energy than the reactants.

Front

In an exothermic reaction, do the reactants or products have higher energy?

Back

The reactants have higher energy than the products.

Front

What is enthalpy change in an endothermic reaction?

Back

The enthalpy change is positive, indicating that energy is absorbed.

Front

What is enthalpy change in an exothermic reaction?

Back

The enthalpy change is negative, indicating that energy is released.

Front

If a beaker feels cold during a reaction, what type of reaction is occurring?

Back

An endothermic reaction is occurring.

Front

If a beaker feels warm during a reaction, what type of reaction is occurring?

Back

An exothermic reaction is occurring.
