Spontaneous Rxn Involving Cl

How do you know that Cl2 (g)--->2Cl (g) is spontaneous only at high temperatures?

In terms of thermodynamics, its Gibbs free energy change would be negative only at high temperatures.

In empirical terms, a bottle of chlorine gas at room temperature does not spontaneously split into chlorine atoms.
