Exercise: Determine AHP and AS for the auto-ionization of water. 2 H₂O Temperature (°C) 0 25 35 40 50 H₂O (aq) + OH(aq) Ln(K₂) Ku 1.14 10 1.00×10 2.09 x 104 2.92 x 104 5.47x10-¹4 Ln(K) = - Hints: 1. The linear equation that correlates the temperature and equilibrium constant is called vant's Hoff equation AH 1 T(K) 3. Take the reciprocal of T(K)- 4. Covert Kw to Ln(K) 5. Obtain the best-fit straight line, slope 8.314 J/mol.k→ AH = -slope x 8.314 6. ASY-intercept x 8.314 R 2. Convert T in °C to T in K, T(K)= T(C) +273 T(K) +45° ΔΗ R since R (ideal gas constant) ==
