find delta H, S, G, lab?

Question

Consider the autoionization of water:
H2O(l) > H+(aq) + OH-(aq)
determine H° and S° for the autoionization of water.
T(C) K
0.0 1.14*10^-15
25 1.00*10^-14
35 2.09*10^-14
40 2.92*10^-14
50 5.47*10^-14

Estimate the value of G° for the autoionization of water at its critical temperature of 374°C

i need more details to figure it out

Answer 1

Use the Henderson Equation.
