### Rate Constants and Temperature

Is there an equation that relates temperature and rate constants?

The Arrhenius equation relates temperature and rate constant, specifically that the rate constant increases for an increase in temperature and vice versa. Remember that in the equation the rate constant depends on the activation energy as well as the temperature in Kelvin.

The equation is written as lnk=lnA-Ea/RT, where R is the gas constant, A is the pre-exponential factor, and Ea is the activation energy. This equation could also represent a negative linear relationship between lnk and 1/T.

yes, the Arrhenius equation (k = A exp( -EA/RT )
