Question

Due: November 27, 2017 Answer the following questions and solve the following problem neatly and completelty. Use extra sheets of paper to show all your work. To solve same problems, you may need thermodynamic data from the tables provided in your textbook. 1. For the chemical reaction o())20e) Hg)AG- 8 kJ at 298 K, 0Jat (a) Calculate the value of the equilibrium constant for this reaction at each of these (b) Calculate the relative partial pressures of the gases under the three different equilibrium conditions.

Explanation / Answer

a)

get K for:

T = 298K

dG = -RT*ln(K)

K = exp(-dG/(RT))

K = exp(-5800/(8.314*298)) = 0.096231

T = 354 K

K = exp(0/(8.314*354 )) = 1

T = 373 K

K = exp(2000/(8.314*373)) = 1.905

b)

finr relative partial pressures of each gas:

Q = P-O2^2 * P-H / (P-O3)(P-OH)

at T = 298K

0.096231 = P-O2^2 * P-H / (P-O3)(P-OH)

P-O2^2 * P-H = 0.096231 *(P-O3)(P-OH)

at T = 354

1= P-O2^2 * P-H / (P-O3)(P-OH)

P-O2^2 * P-H = (P-O3)(P-OH)

at T = 373

1.905 = P-O2^2 * P-H / (P-O3)(P-OH)

P-O2^2 * P-H = 1.905 (P-O3)(P-OH)
