The chemical reaction: glucose (G) + galactose (A) lactose (L) + H 2 O (W) Has an equilibrium constant of Keq= 3.5 x 10 -1 What does that mean about the amount of reactants and products when the reaction nears equilibrium? (assume the size of the lettering represents the relative concentration of molecules)

The chemical reaction: glucose (G) + galactose (A) lactose (L) + H 2 O (W) has an equilibrium constant of K eq= 3.5 x 10 -1 What does that mean about the chemical reaction when it is at equilibrium? The size of the arrows represents the rate of the reactions and the size of the lettering represents the concentration of the reactants and products.
