I know Dr. Lavelle said most of the time we'll be working with systems at equilibrium, but how will we know when a system is not at equilibrium unless it's stated? Would being given the boiling point of the system be one indicator of equilibrium always (since it's where the liquid and gas phase coexist)?
Another thing that we can look at to determine this is by looking at the deltaG of the products vs the reactants. When both of these two values equal each other then we know that the reaction is at equilibirum. If not then we can calculate the reaction quotient and see how the reaction will proceed
Calculating a negative deltaG means that the reaction is favorable in the forward direction. However, if you get a positive deltaG, this means the current direction is unfavorable, so it would proceed in the reverse direction.
