How does one go about calculating delta G in standard conditions given the individual pressure values of reactants and products?

The reaction doesn't say what type elements are involved and i found the Keq given a delta G in the previous question

>inb4 banned for homework, i'm studying for my test

I would just like to know what formula i'd apply for this

lolwut

how does that apply?

I used that to find my Keq initially but i don't see how that can be used when i'm given pressure now. I'd still have to apply the K i found previously but with pressure being introduced it wouldn't give me the right answer

Equilibrium constants can be expressed in the partial pressures of the products over the partial pressure of reactants.

ah see.

i didn't know i could just use the partial pressures and neglect the K value
