Details
Equation:
rT = \frac{1}{\frac{1 + e^{\frac{cc}{1.987} * (\frac{1}{dd} - \frac{1}{T + 273.16})}}{aa*\frac{T + 273.16}{298.15}*e^{\frac{bb}{1.987}*(\frac{1}{298.15} - \frac{1}{T + 273.16})}}}
where rT is the development rate, T the temperature, and aa, bb, cc, and dd are thermodynamic parameters.
