### Catalyst

Would adding a catalyst to a reaction change the value of K?

A catalyst increases k, but it does not affect K because the ratio of products to reactants remains the same.

### Re: Catalyst

no; adding a catalyst lowers activation energy, which increases the rate constant k because the reaction could proceed faster. however, i believe the rates of the forward and reverse reaction would increase proportionally, so mathematically you can see the equilibrium constant K is unaffected
