Mercury(I) oxide decomposes into elemental mercury and elemental oxygen:.(a)Write the equilibrium-constant expression for this reaction in terms of partial pressures.(b) Suppose you run this reaction in a solvent that dissolves elemental mercury and elemental oxygen. Rewrite the equilibrium-constant expression in terms of molarities for the reaction, using (solv) to indicate solvation.
