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 individual molecules could be seen. (The water molecules are not shown.) 8 R and P can interconvert. That is, R can turn into P, and P can turn back into R: 113 5 R (aq)=P(aq) R P number of R molecules: number of P molecules: K= The equilibrium constant K for this equilibrium is interconversion reaches equilibrium. $3/1₁ Predict the number of R and P molecules in this sample when the .
