Answer #1

The plot of ln(Pwater) versus 1/T can be drawn as follows.

ln(Pwater) = -4462.52556*(1/T) + 11.80159

The actual equation: ln(Pwater) = (-\DeltaHo/R)(1/T) + \DeltaSo/R

Here, \DeltaHo/R = 4462.52556 K

i.e. \DeltaHo = 4462.52556 K * 8.314 J/mol.K = 37.101 kJ/mol

And \DeltaSo/R = 11.80159

i.e. \DeltaSo = 11.80159*8.314 J/mol.K = 98.118 J/mol.K

Now, the percentage error in \DeltaHo = {(44 - 37.101)/44}*100 = 15.68%

And the percentage error in \DeltaSo = {(118.9 - 98.118)/118.9}*100 = 17.48%
