2. Relevant equations

3. The attempt at a solution

Does 'magnitude (in kJ/mol) of energy barriers to rotation from anti to gauche' mean the difference in energy?
This question is asking for the magnitude of energy barriers to rotation about the bond between two carbons from anti to gauche. Do I just subtract gauche energy from anti?

What is the difference between the two conformers? Use actual values only if you are provided with them.

ABSOLUTELY NOT!!!!

The barrier to rotation has absolutely nothing to do with the energy of the individual confomers.
