(i) Enter a known reaction temperature (Temperature 1) and time (Time 1)

then either:

(ii) Enter a new reaction temperature (Temperature 2) and click “Calculate” to give the corresponding new reaction time (Time 2)


(iii) Enter a new reaction time (Time 2) and click "Calculate" to give the required temperature (Temperature 2).


Calculations use the Arrhenius equation with a null frequency factor (A) and an Activation Energy (EA) of 50kJ mol-1

Known reaction temperature and time:

Temperature 1:  °C                      Time 1: ::: (days) (hr) (min) (sec)
Unknown reaction temperature or time:

Temperature 2:  °C                      Time 2: ::: (days) (hr) (min) (sec)
