arrhenius equation calculator

the arrhenius equation expresses the fraction of collisions with sufficient energy to overcome the activation barrier (ie, energy greater than or equal to the activation energy ea) at a given temperature t. it is used to determine the effect of temperature on the rate of reaction outcomes.
