✦ Synopsis

yield values of the equilibrium constant for LiOH ~ Li + OH [9] when combined with calculated values of the equilibrium concentration of hydroxyl [OH]e. A plot of log { [OH]Jt~[.i } is shown in Figure 3. The results are seen to be in excellent agreement with the line drawn which represents the dissociation constant K9 derived by Jensen and Padley 8 using a 'Third Law' method.

An interesting point which therefore emerges from this work is that if, as the evidence suggests. the addition of sulphur results in the rapid establishment of equilibrium in these flames, it should be possible to measure the dissociation constants of the gaseous alkali metal hydroxides over a wide range of temperature and hence derive the heats of dissociation by a 'Second Law' method which, due to the disequilibrium, is not normally possible in hydrogen flames.
