Answer:

Question

The following questions refer to the following reaction at constant 25°C and 1 atm.

2Fe(s) + (3/2)O2(g) + 3H2O(l)  2Fe(OH)3(s) H = –789 kJ/mol

Substance S° (J/mol K)

Fe(OH)3(s) 107

Fe(s) 27

O2(g) 205

H2O(l) 70

a. Determine Ssurr for the reaction (in kJ/mol K)

b. Determine Suniv for the reaction (in kJ/mol K)2.65

c. What is the G for this reaction?

d. Calculate the equilibrium constant
