Which statement is correct for the reaction represented below? $2\mathrm{NOCl}\left(g\right)⟶2\mathrm{NO}\left(g\right)+{\mathrm{Cl}}_2\left(g\right);\mathrm{\Delta }{H}_{\text{reaction }}^{\circ }>0$ This reaction is:

Statement B is correct for the given reaction are,

$2\mathrm{NOCl}\left(g\right)⟶2\mathrm{NO}\left(g\right)+{\mathrm{Cl}}_2\left(g\right);\mathrm{\Delta }{H}_{\text{reaction }}^{\circ }>0$ 

This reaction is spontaneous only at high temperatures.
