Getting Gibbs Free Energy in terms of T and P
« on: November 01, 2010, 11:31:19 PM »
I am trying to Getting Gibbs Free Energy in terms of T and P.  and so far I've gotten to

G2-G1 = - (integral from T1 to T2 of)S dT
I don't get what happens for the part where it says that "For biological processes at body temperature (37oC = 98.6oF)"

it shows 2 delta Gs subtracting each other which doesn't make any sense to me??? and if we have swapped over to standard entropy why would we be subtracting G2-G1?

Direct link to my notes (I am stuck on understanding page 11-)

Thank you

The free energy should be different at different temperatures.  However the standard entropy is constant at both temperatures as long as the pressure is constant.
