Exothermic and Endothermic

Question 1

what is an exothermic reaction

Answer 1

a reaction that releases heat energy to the surroundings and hence forms bonds (FEELS HOT)

Question 2

What is enthalpy

Answer 2

enthalpy of stored chemical energy is the amount of energy in a substance aka heat

Question 3

Explain the enthalpy of an exothermic reaction

Answer 3

energy is released and the products have lower enthalpy than the reactants = energy required is less than energy released

Question 4

what is an endothermic reaction

Answer 4

a reactions that absorbs heat from surroundings and breaks bonds ( FEEL COLD)

Question 5

Explain the enthalpy of an endothermic reaction

Answer 5

energy is absorbed and the products have higher enthalpy than the reactants = energy required is less than energy released

Question 6

What are two examples of endo reaction

Answer 6

photosynthesis, evaporation

Question 7

What are two examples of exo reaction

Answer 7

combustion and respiration
