To examine the extent that water spontaneously decomposes to its elements at room temperature, consider that the standard Gibbs energy of formation (∆G ̊f) of H2O (l) is –237.20 kJ/mol. Use this information to calculate the equilibrium constant for the decomposition of water at 298 K:
2 H2O (l) ⇄ 2 H2 (g) + O2 (g)
a) 7.0 x 10 –84
b) 2.6 x 10 –42
c) 0.91
d) 3.8 x 1041
e) 1.4 x 1083
