However, the catalyst thus … WebFor ionic compounds with limited solubility in water, an equilibrium constant, Ksp, can be defined from the ion concentration in water from the equation: MmAn(s) = mMn+(aq) + nAm-(aq) where M m A n is the slightly soluble substance and M n+ and A m- are the ions produced in solution by dissosiation of M m A n. Ksp = [Mn+]m * [Am-]n
WebIron (III) oxide by itself is unselective producing carbon dioxide and water; molybdenum trioxide is selective but with low activity [5]. The overall reaction is The oxidation reaction is exothermic (ΔH=-159 kJ mol -1) and proceeds through reaction of methanol with the molybdate surface [6].
