Atiny sample of an aqueous solution of two substances r and p is sketched below as if it was under an imaginary microscope so powerful that molecules could be seen. (the water molecules are not shown.) r and p can interconvert. that is, r can turn into p, and p can turn back into r 2 the equilibrium constant k for this equilibrium is. predict the number of r and p molecules in this sample when the interconversion reaches equilibrium. a number of r molecules: d number of p molecules:
