### Question for Dr. Lavelle - 14C/D

Dr. Lavelle,

Can you teach Chem 14C/D too? Would love to have you as my professor again.

### Re: Question about approximation of results

Let's say K is equilibrium constant for GAUCHE BUTANE<-> ANTI BUTANE at 373K. K=3.6. When interpreting this, which is more correct: 4 anti conformations for each 5 conformations or 36 anti conformations for each 46 conformations

### Question about approximation of results

Let's say K is 3.6 for a molecule. Would we approximate and say that for 4 anti conformations we have 1 gauche or should we say for 36 anti conformations we have 10 gauche?

Oh, never mind. Exothermic reactions are favored in forward direction.

For $\Delta H+$ on page 41 course reader, can somebody explain why this does not favor the forward process?

Thanks.
