The standard entropy of liquid methanol at 298K is 126.8 J/K-mol and its heat capacity is 81.6 J/K-mol. Methanol boils at 337K w

USPshnik [31]

Explanation:

First, we will calculate the entropies as follow.

$\Delta S_{2} = C_{p_{2}} ln \frac{T_{2}}{T_{1}}$ J/K mol

As, $T_{1}$ = 298 K, $T_{2}$ = 373.8 K

Putting the given values into the above formula we get,

$\Delta S_{2} = C_{p_{2}} ln \frac{T_{2}}{T_{1}}$ J/K mol

= $81.6 ln (\frac{373.8}{298})$

= 18.5 J/K mol

Now,

$\Delta S_{3} = \frac{\Delta H_{vap}}{T_{b.p}}$

= $\frac{35270 J}{373.8}$

= 94.2 J/mol K

Also,

$\Delta S_{4} = C_{p_{4}} ln \frac{T_{2}}{T_{1}}$

= $43.89 \times ln (\frac{800}{373.8})$

= 33.4 J/K mol

Now, we will calculate the entropy of one mole of methanol vapor at 800 K as follows.

$\Delta S_{T} = \Delta S^{o}_{1} + \Delta S_{2} + \Delta S_{3} + \Delta S_{4}$

= (126.8 + 18.5 + 94.2 + 33.4) J/K mol

= 272.9 J/K mol

Thus, we can conclude that the entropy of one mole of methanol vapor at 800 K is 272.9 J/K mol.
