The temperature reaction changes from spontaneous to nonspontaneous?

How do you calculate the temperature a reaction changes from non-spontaneous to spontaneous? Is it at the point where the reaction reaches equilibrium?

You use the equation delta G = delta H - Tdelta S, and by plugging in your known values of delta H and S, you make G equal to zero and solve for T. That temperature, T (when G = 0) is when the reaction changes from nonspontaneous to spontaneous and vice versa.
