Chemical Thermodynamics Question 407

Question: For the auto-ionization of water at 25C,

H2O(l)H+(aq)+OH(aq) equilibrium constant is 1014 . What is ΔG for the process-

Options:

A) 8×104Jmol1

B) 3.5×104Jmol1

C) 2×104Jmol1

D) None of these

Show Answer

Answer:

Correct Answer: A

Solution:

  • ΔG=RT ln K =8.314JK1,mol1×298K×2.303log1014

=7.98×1048×104J,mol1
