A tiny 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:
