Determining the equilibrium constant

[Spencer Cutrow 1A]

If we are given a molecule with 4 confirmations, like butane, will we ever be asked to determine multiple equilibrium constants at once. If so, Is there anything we can tell by looking at the equilibrium constant between two confirmations which are not directly next two each other?

If they ask you to determine multiple equilibrium constants, then you're gonna have to determine multiple equilibrium constants (sorry, I have no idea what the final's gonna look like).

Check out page 111 in your course reader. Basically you're gonna solve for K_eq using the equation deltaG = -RT*ln(K_eq).
You know that R is the gas constant, and T will be provided to you. All that's left is to find deltaG.
deltaG is going to be a difference in energies. If your'e finding the K_eq for gauche to eclipsed conformation, the you'll use their energy difference as deltaG. If you're finding the K_eq for anti to gauche, then you'll do the same as before and get the difference in energy as your deltaG.
