Final answer:

Potassium ions leave the cell due to electrochemical gradients until the electrical gradient stops further efflux. Chemical potential gradient drives the outward flow of potassium ions.

Explanation:

Electrochemical gradients drive potassium out of the cell until the electrical gradient opposes further net efflux of potassium. The chemical potential gradient causes the outward flow of potassium ions, leading to the development of a transmembrane potential that resists further potassium efflux.
