Question

Calculate the equilibrium constant (Is_p) for the reaction I_2 (g) 2I(g) at 500, 1000, and 2000 k. Use the following spectroscopic parameters, and assume the rigid-rotor and harmonic oscillator approximations. Show the calculation of the thermal wavelength for I atoms and I_2 molecules at each temperature, and the rotational and vibrational temperatures for I_2. One you have determined the values of K_p, construct a plot of ln k_p vs. 1/T and determine the value of Delta_ber H degree for the reaction. Does the value mate 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.

Explanation / Answer

Tabulate the K and T values are as follows:

1/T

ln K

7.50E+04

500

0.002

11.22524339

1.08E+05

1000

0.001

11.58988651

1.54E+05

2000

0.0005

Plot the 1/T vs lnK as follows:

1/T is taken on x-axis, and lnk is taken on y-axis.
