    I AM TRYING TO FIND THE ACTIVATION ENERGY
    My slope is (-4295.5)
    My R is the Gas constant=8.314

    How do I utilize the Arrhenius formula to get the Activation energy? Also, how do I calculate th slope of log K compared to 1/Temp?

    This is called an Arrhenius plot where you plot lnk vs. 1/T to get the activation energy. The reference could be found here:
    http://en.wikipedia.org/wiki/Arrhenius_equation

    The equation is:
    lnk = lnA - (Ea/R)*(1/T)
    This means the slope of your plot is = -Ea/kb
    where kb is the Boltzmann constant.

    So plot out the values as in the attached excel file. Using the fitting trendline feature, you arrive with the slope = -4295.5
    Thus -4295.5 =-Ea/8.314
    Ea = 35,712 (J/mol)
