Problem Details

Given the following free energies of formation calculate K p at 298 K for:

C2H(g) + 2 H(g) → C2H(g)

C2H2(g)      ΔG°f = 209.2 kJ/mol

C2H6(g)      ΔG°f = -32.9 kJ/mol

a) 9.07 x 10 –1

b) 97.2

c) 1.24 x 10 31

d) 2.74 x 10 42

e) None of these is within a factor of 10 of the correct answer.
