Consider the decomposition of liquid hydrogen peroxide (H₂O₂) to form water and oxygen.

a. What is the heat of formation for hydrogen peroxide?

b. What is the heat of formation for liquid water?

c. What is the heat of formation for gaseous oxygen? Why?

d. Write the balanced chemical equations that correspond to the ΔH values you looked up for parts a, b, and c.

e. Write the balanced chemical equation for the decomposition of hydrogen peroxide to form water and oxygen. (Write the equation such that the coefficient on oxygen is 1.)

f. What is the heat of reaction for the process in part e?

g. Draw a scale diagram of this reaction (1 cm = 100 kJ) that shows the relative energies of reactants (on the left), products (on the right), and the elements in their most stable states (in the middle). Label all the energies you know.
