Tiny samples of aqueous solutions are sketched below, as if under a microscope so powerful that Individual molecules could be seen. (The water molecules are not shown.) The two substances in each sample can interconvert. That is, each kind of molecule can turn into the other. The equilibrium constant K for each interconversion equilibrium is shown below the sketch. Decide whether each solution is at equilibrium. At equilibrium? O no O yes K-11 At equilibrium? O no O yes X
