Does C6H4Cl2 Produced in Reaction 2 Get Consumed in Reaction 3?

[man0005]

Homework Statement

For the production of chlorobenzene reaction:
1) C6H6 (l) + Cl2(g) → C6H5Cl (l) + HCl (g)
2) C6H5Cl (l) + Cl2(g) → C6H4Cl2(l)+ HCl (g)
3) C6H4Cl2 (l)+ Cl2 (g) → C6H3Cl3(l) + HCl (g)

Is any of the C6H4Cl2 produced in reaction 2 used up in reaction 3?
