For the reaction of H2(g) with Cl2(g) as shown in the diagram, how do you know which half reaction to reverse?

The reaction on the right is always going to be a reduction reaction and the reaction on the left is always going to be an oxidation reaction. For the question, you would flip the right side to get the equation Cl2+2e- ---> 2Cl- which is a reduction reaction.
