### Steric Contribution

Why does the steric contribution make $\Delta S^{\ddagger }$ an unfavorable, negative value? If it prevents molecules from combining, doesn't that increase entropy, making it a positive value?

### Re: Steric Contribution

The steric contribution does prevent molecules from combining as the orientations of the reactants will be specified which means there will be less disorder, so entropy decreases(a negative value) and is unfavorable.
