Document Summary
An increase in k correlates with an increase in temperature. These two factors increasing also causes a faster rate. Temperature is dependant on the reaction based on the k value. So one could say that temperature is more so k dependant. Is an expression which relates the rate constant (k) to the temperature (t) in kelvin. Make sure to remember that to get kelvins for you temperature you have to add 273. 15 to your celcius value. This will give you your temperature in kelvin. To solve for the rate constant, activation energy, or your frequency factor you can use k = ae^ ea /rt. Where k= rate constant and the units depend on order, a= frequency factor/pre-exponential factor, and ea= activation energy where the units are typically kj/mol or j/mol. The formula to find the pre-exponential factor is f = e^-ea/rt. The exponential factor is a fraction of molecules with enough energy to react.
