ABSTRACT
Which is a four-parameter model. To determine these four constants, we first plot ln 11 versus time at each temperature. The slope and intercept of these plots yield k and 11o respectively. The natural logarithm of each of these quantities is then plotted as a function of I IT: the required constants are obtained from the slope and intercept of these two staight lines according to Eq. (15.4) and ( 15.5).
