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.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
