Explanation / Answer

1.

G = Gprod - Greact = 0 - -9.8 = 9.8 kJ/mol

2.

G = -RT*ln(K)

K = exp(-G/(RT))

K = exp(-9800/(8.314*298))

K = 0.0191493

3.

P-O2

Kp = P-O2 ^(1/2)

Kp = Kc*(RT)^dn

dn = 1/2

Kp = 0.0191493*(0.082*298)^1/2 = 0.2339

Kp = 0.2339

Kp = P-O2 ^(1/2)

0.2339 = P-O2 ^(1/2)

PO2 = 0.2339 ^2 = 0.054709 atm
