The value of
the rate constant depends on the orientation factor,
activation energy and temperature. The rate constant is given by
k = A e -Ea/RTE
a is the activation energy, R is the gas constant and T is the temperature in Kelvin. This is known as the Arrhenius Equation.
Every straight line can be written in the form y = mx + c
The Arrhenius equation gives an exponential curve. But rearranges in the form of a straight line if you use the natural logarithms.
Plot ln k against (1/T)
| y | = | m | x | + | c |
| ln k | = | -Ea/R | 1/T | + | ln A |
