A graph of this equation's terms natural log of k and 1 over T results in a straight line with a gradient of its exponential term. This equation uses a term called the frequency factor, which varies with the temperature, though its variance is small in relation to the exponential term, so it can be considered a constant. The other constants that appear in the equation are the Stefan-Boltzman constant, Euler's constant, and a constant based on how many ways the molecules can combine. FTP, name this equation that relates the rate constant, the ambient temperature, and the activation energy of a reaction.
