Calculate the gibbs energy of freezing (deltagfreezing) in units of j/mol when supercooled water freezes at -3degreec at constant t and p. delta h fusion = 6000 j/mol at 0degreec. the molar heat capacity of water and ice are 75.3 j/molk and 38 j/molk, respectively, and both are independent of temperature over this range. state any assumptions you make in your calculation!

Explanation:

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

                             =

                 (assumption)

                     =

                     =

As, T = = (-3 + 273) = 270 K,   .

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

=

                  = -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.
