And what that implies is the only way that this concentration is not changing is if this reaction going this way if the formation of the enzyme substrate complex is equal to the dissociation of that enzyme substrate complex. So assuming the steady state condition, the concentration of the enzyme substrate complex will remain constant. And this means that the rate of formation of the enzyme substrate complex is the same of the rate as the rate of dissociation. So equation number two is equal to equation number three because we make this assumption of a steady state condition. So once again, a steady state condition means this concentration remains unchanged. And the only way that's true is if this K one reaction is equal to these two reactions here.
