What is the purpose of th gibbs free energy equation you don't need to know the equation itself?
The purpose is to determine the available energy. Some of the energy in any system is useless - can't be converted into useful work.
How will temperature affect the spontaneity of a reaction with positive triangle H and triangle S?
For a reaction with a positive enthalpy change (ΔH > 0) and a positive entropy change (ΔS > 0), the spontaneity is influenced by temperature through the Gibbs free energy equation: ΔG = ΔH - TΔS. As temperature increases, the TΔS term becomes larger, which can make ΔG more negative, thereby favoring spontaneity. Therefore, at higher temperatures, the reaction is more likely to be spontaneous, while at lower temperatures, it may not be spontaneous.
Why would a project have a negative NPV?

Can the gravitational potential energy of an object ever have a negative value?
it is conventional to define gravitational potential energy (GPE) of object A to be 0 when the object is free from the gravitational field of object B (i.e. at a infinite distance away) As the objects get closer together, the GPE decreases, thus is less than 0. Therefore the GPE of any object normally has a negative value (however it all just depends on where you define to be the point at which the object has 0 GPE)
Why Ellingham diagram slopes upwards?
change in free energy is positive
