Question

How do the three reactions relate to each other? Also, how do the given enthalpy values relate to the one that I am supposed to find?

The 1995 Nobel Prize in Chemistry was shared by Paul Crutzen, F. Sherwood Rowland, and Mario Molina
for their work concerning the formation and decomposition of ozone in the stratosphere. Rowland and
Molina hypothesized that chlorofluorocarbons (CFCs) in the stratosphere break down upon exposure to
UV radiation, producing chlorine atoms. Chlorine was previously identified as a catalyst in the breakdown
of ozone into oxygen gas.
Using the enthalpy of reaction for two reactions with ozone, determine the enthalpy of reaction for the
reaction of chlorine with ozone.
