If there's a pair of electrons in the elements shared by atoms, the elements are taking part in covalent bonding.

Calculate the Gibbs energy of freezing (DeltaGfreezing) in units of J/mol when supercooled water freezes at -3degreeC at constan

frutty [35]

Explanation:

It is known that the change in Gibb's free energy varies with temperature as follows.

$\Delta G(T) = \Delta H(T) - T \Delta S(T)$

= $\Delta H(T_{f}) - \Delta C_{p,m} (T - T_{f}) - T[\Delta S(T_{f}) - \Delta C_{p,m} ln (\frac{T}{T_{f}})]$

$\Delta H(T_{f}) = -\Delta_{fus} H(T_{f})$ (assumption)

= $\Delta H(T_{f}) - \frac{T}{T_{f}} \Delta H(T_{f}) - \Delta C_{p, m}(T - T_{f} - T ln \frac{T}{T_{f}})$

= $(\frac{T}{T_{f}} - 1) \Delta_{fus} H(T_{f}) - \Delta C_{p,m}(T - T_{f} - Tln (\frac{T}{T_{f}}))$

As, T = $-3^{o}C$ = (-3 + 273) = 270 K, $T_{f} = 0^{o}C = 0 + 273 K = 273 K$ .

Therefore, calculate the change in Gibb's free energy as follows.

$\Delta G(T) = (\frac{T}{T_{f}} - 1) \Delta_{fus} H(T_{f}) - \Delta C_{p,m}(T - T_{f} - Tln (\frac{T}{T_{f}}))$

= $(\frac{270 K}{273 K} - 1)(6000 J/mol K) - (75.3 - 38) J/mol K (270 K - 273 K - 270 K ln \frac{270 K}{273 K})$

= -65.93 J/mol K + 0.62 J/mol K

= -65.31 J/mol K

Thus, we can conclude that Gibbs energy of freezing for the given reaction is -65.31 J/mol K.

denpristay [2]

The building with incandescent light bulbs would have higher energy bills because less than 10% of the bulb is used for light while the rest is given off as heat. Fluorescent light bulbs use ¼ as much energy and provide the same amount of light.
