Hydrogen Iodide Can Theoretically Be Made by the Reaction of Hydrogen

Hydrogen iodide can theoretically be made by the reaction of hydrogen gas and iodine by the following reaction:
H₂(g) + I₂(s) $\to$ 2HI(g)
What temperature conditions are required for the formation of HI to be favored at standard pressure?
S ^$\circ$ (H₂, g) = 130.6 J/(mol. K)
S ^$\circ$ (I₂, s) = 116.1 J/(mol . K)
S ^$\circ$ (HI, g) = 206.6 J/(mol . K)

(HI, g) = 26.5 kJ/mol
