Calculate the equilibrium constant (AT,,) lor the reaction I2(g)right arrow left

Question

Calculate the equilibrium constant (AT,,) lor the reaction I2(g)right arrow left arrow2I(g) at 500, 1000, and 2000 K. Use the following spectroscopic parameters, and assume the rigid-rotor and harmonic oscillator approximations. (Note that most of the parameters for the I2 molecule could have been derived from the spectroscopic data that you analyzed in the last problem set, although the actual value of D0 listed below is less than what you determined by assuming the Morse potential.) Show that calculation of the thermal wavelength A for I atoms and I2 molecules at each temperature, and the rotational and vibrational temperatures for I2. Some of these quantities are tabulated in McQuarrie and Simon you can obviously check your result - but show the calculation for each Data for I2 Once you have determined the values of construct a plot of In Kp vs. 1/T and determine the value of Delta r mulptiples for the reaction. Does this value make sense based on the spectroscopic data listed above? Also - compare your values of the equilibrium constants with those determined from the thermodynamic information in the following table (copied from Silbey et al. Physical Chemistry' 4"' edition) Delta rxn G degree = -RT in K in K=delta rxn s degree/R-delta rxnH degree/ RT
