🤓 Based on our data, we think this question is relevant for Professor Lewis' class at UGA.
We need to use the two-point form of the Arrhenius Equation:
k = rate constant
Ea = activation energy (in J/mol)
R = gas constant (8.314 J/mol • K)
T = temperature (in K)
A = Arrhenius constant or frequency factor
Hydrogen iodide, HI, decomposes in the gas phase to produce hydrogen, H2, and iodine, I2. The value of the rate constant, k, for the reaction was measured at several different temperatures and the data are shown here:
What is the value of the activation energy (in kJ/mol) for this reaction?
