At 298 k the standard enthalpy of combustion of sucrose is -5645 kj/mol and the standard reaction gibbs energy is -5798 kj/mol. assume ∆h does not change to estimate the additional non-expansion work that may be obtained by raising the temperature to blood temperature, 37o c. enter your answer in kj/mol to two significant figures and do not enter the units.

Explanation:

The given data is as follows.

             T = 298 K,           = -5645 kJ/mol

          = -5798 kJ/mol

Relation between and are as follows.

          =    

             -5798 kJ/mol = -5645 kJ/mol -

                       -153 kJ/mol = -

                    = 0.513 kJ/mol K

Now, temperature is = (37 + 273) K = 310 K

Since,         =

                            =

                            = (-5645 kJ/mol - 159.03 kJ/mol)

                            = -5804.03 kJ/mol

As, change in Gibb's free energy = maximum non-expansion work

                           = -5804.03 kJ/mol - (-5798 kJ/mol)

                           = -6.03 kJ/mol

Therefore, we can conclude that the additional non-expansion work is -6.03 kJ/mol.
