For the reaction $2Cl (g) \to C l_{2} (g)$ , the correct option is:

A. $Δ_{r} H > 0$ and $Δ_{r} S > 0$
B. $Δ_{r} H > 0$ and $Δ_{r} S < 0$
C. $Δ_{r} H < 0$ and $Δ_{r} S > 0$
D. $Δ_{r} H < 0$ and $Δ_{r} S < 0$ ✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
