Organize the reacts and products given to you such that you create a Born-Haber Cycle.  Ensure that if the process is endothermic you connect with an arrow going up and if it’s an exothermic process you connect with an arrow going down.

The specific values for the processes are given to you in a separate post.  Once the diagram is complete, use them to calculate the electron affinity for chlorine.
