Arrhenius Equation & Rates Of Reaction

The higher the temperature, the faster a given chemical reaction will proceed. The Arrhenius equation is the mathematical expression that describes the effect of temperature on the velocity of a chemical reaction, and it is the basis of all predictive expressions used for calculating reaction-rate constants:

     k = Ae^-E/RT

where
     k = reaction rate constant
     A = frequency factor, constant characteristic of reacting substances
     E = heat energy of activaction, constant characteristic of reacting substances
     R = universal gas constant = 8.314472 J·K^-1·mol^-1
     T = temperature, °K
