Time-acceleration factor as a function of temperature differential factor from Table 18.2 and activation energy Ea 18.3.2 Eyring Relationship Time-Acceleration Factor he Arrhenius relationship (18.1) was obtained through empirical observation. Eyring Eyring, Gladstones, and Laidler, 1941, or Eyring, 1980) gives physical theory describing the effect that temperature has on a reaction rate. Written in terms of a reaction rate, -E R(temp) = yX A(temp) X exp ka X temp K where A(temp) is a function of temperature depending on the specifics of the reac- tion dynamics and yo and E, are again constants (e.g., Weston and Schwarz, 1972, provide more detail). Applications in the literature have typically used A(temp) (temp K) with a fixed value of m ranging between m =0 (Boccaletti et al., 1989, page 379), 5 (Klinger, 1991a), to m= 1 (Nelson, 1990a, page 100; Mann, Schafer, and Singpurwalla, 1974, page 436). Time-Acceleration Factor 10

Answer 1

The life-temperature relationship plots as a family of straight lines because temperature is plotted on an Arrhenius axis and life is plotted on a log axis. The densities are normal densities because the lognormal life distributions are plotted on a log axis.
