Re: Kinetically controlled reaction

Under kinetic control- 1)The product proportion reflects the relative rates of formation of the processes. 2)The reaction can be under kinetic control before equilibrium conditions are established. Under thermodynamic control- 1) The product proportion reflects the relative free energies of the prod...

Treating Systems that have Small Equilibrium Constants

Hi Chem community!
I apologize in advance if this has been posted/answered. I'm just a little confused on why we can approximate when solving for equilibrium concentrations if K is super small.
Thank you very much (:
