Physical Biochemistry Review Flashcards
What are the three types of work in living systems
Osmotic work, Chemical work, and mechanical work
What is the zeroth law of thermodyamics
If two systems are in thermal equilibrium with a third, then they are in thermal equilibrium of one another
What is the first law of thermodynamics
Energy can neither be created nor destroyed
What is the second law of thermodynamics
total entropy can never decrease over time for an isolated system, that is, a system in which neither energy nor matter can enter nor leave.
What is the third law of thermodynamics
As temperature approaches absolute zero, the entropy of a system approaches a constant minimum
What is the delta G of a spontaneous reaction
negative
What is the equation for the relationship between the three thermodynamic qualities
H= G +TS OR G= H= TS
What is the equilibrium constant equation
Keq = [B] / [A]
What is the equation for Go’
= -RTlnK’eq
What is the mass action ratio
Q= [C]c[D]d/ [A]a{B]b
