Questions and Answers
What is an exothermic reaction?
What is an exothermic reaction?
- A reaction that releases more energy when new bonds form in the products than is needed to break bonds in the reactants
- A reaction that releases energy when new bonds form in the products (correct)
- A reaction that requires energy to break bonds in the reactants
- A reaction that releases less energy when new bonds form in the products than is needed to break bonds in the reactants
What is the difference between exothermic and endothermic reactions?
What is the difference between exothermic and endothermic reactions?
- Exothermic reactions release less energy when new bonds form in the products than is needed to break bonds in the reactants, while endothermic reactions release more energy when new bonds form in the products than is needed to break bonds in the reactants
- Exothermic reactions require energy to break bonds in the reactants, while endothermic reactions release energy when new bonds form in the products
- Exothermic reactions release more energy when new bonds form in the products than is needed to break bonds in the reactants, while endothermic reactions release less energy when new bonds form in the products than is needed to break bonds in the reactants
- Exothermic reactions release energy when new bonds form in the products, while endothermic reactions require energy to break bonds in the reactants (correct)
What happens to energy in an exothermic reaction?
What happens to energy in an exothermic reaction?
- Less energy is used to break bonds in the reactants, and more energy is released when new bonds form in the products
- Less energy is used to break bonds in the reactants, and less energy is released when new bonds form in the products
- Energy is used to break bonds in the reactants, and more energy is released when new bonds form in the products (correct)
- Energy is used to break bonds in the reactants, and less energy is released when new bonds form in the products
