example 9.16 [ENDORSED]

[Liam Maxwell 2E]

the question asks you to estimate the temperature at which it is thermodynamically possible for a reaction to occur. In the explanation it says when temp is increased there is a point where T= standardH/standardS. However in order for this to be true following the equation StandardG=StandardH-TstandardS wouldn't that mean G is 0 and therefore the equation is at equilibrium and therefore the reaction won't have a net occurence?

Solving for the point at which is indeed the condition for equilibrium. To be precise, you are solving for this point so you can describe the inequality. It is the > or < that we are interested in. However, to know this, we must first determine the equilibrium temperature as you wrote.
