rise of temperature was programmed so that the reciprocal of the temperature varied logarithmically with time according to

To T

where T0 and Tt are the temperatures at zero time and at time t, respectively, and b is any suitable proportionality constant. Applying the Arrhenius equation at both temperatures and subtracting gives log kt = log Ko +
