Estimate how an Arrhenius rate constant changes between two absolute temperatures. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.
k_2/k_1 = exp[-E_a/R(1/T_2-1/T_1)]

Activation energy and pre-exponential factor are treated as constant over the temperature interval.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
