A formula is titled "Arrhenius Reaction Rate Theory".  The equation
contains an exponential term which is subtracted from the ratio of the
reaction rate at temperature T to the Reaction rate at reference temperature 
T zero.  The power appearing in the exponential term is negative.  The
power-term is equal to the ratio of the activation energy, in electron volts,
to Boltzmann's constant (8.617x10E5 electron volts per degrees Kelvin), 
multiplied by the inverse of T zero subtracted from T.

An uncaptioned plot shows an example of the Arrhenius reaction rate theory
in use.  The abscissa of the plot is labeled "Junction temperature in degrees
centigrade (reference temperature equal 25 degrees centigrade)".  The range
of data on the abscissa is between 20 and 140, with tick marks at 20-degree 
increments.  The ordinate of the plot is labeled "Piece-Part Reaction Rate
(Reference temperature to 25 degrees centigrade)".  The ordinate is on a
logarithmic scale and the range of data is between 1 and 100000, with tick
marks at multiples of 10.

Three non-linear plots are shown with all three having a common origin at
(25 and 1) coordinates.  The plots represent the reaction energy of 0.3, 0.7
and 1.0 electron volts, respectively.  The plots have a positive slope,
however, each has different amplitude.  The plot representing the 0.3
electron volts energy has the lowest amplitude; the plot with 1.0 electron
volts energy has the highest amplitude.

Three lines are drawn vertically from the abscissa at 60, 85 and 110 degree
centigrade junction temperature. The lines are shown to intersect all three plots.
