What can be deduced about the relative stability of the reactants and products and the sign of AW, from the enthalpy level diagram below ... [Pg.197]

Figure 6.12 a General enthalpy level diagram for uncatalysed and catalysed reactions of an exothermic reaction, b The mountain pass analogy for the mechanism of catalytic action stressing the idea of the creation of an alternative reaction pathway... [Pg.204]

Lattice enthalpies cannot be found directly from experiments (partly because ionic crystals form ion pairs when heated, not free gaseous ions). Therefore lattice enthalpies must be calculated indirectly from other known enthalpy changes of reaction using a Born-Haber cycle. This is an enthalpy level diagram derived from Hess s law it is used to follow the enthalpy changes which occur when an ionic compound is formed from its chemical elements and gaseous ions (Figure 15.11). [Pg.528]

Figure 15.22 is an enthalpy level diagram that shows the processes which occur when silver chloride, an almost insoluble salt, is placed in water. Figure 15.23 is an energy level diagram that shows the processes which occur when silver fluoride, a very soluble salt, is placed in water. Note the larger positive enthalpy of solution for silver chloride compared to silver fluoride. [Pg.533]
