Chapter 3 Flashcards
what are the two factors that determine whether a reaction will occur spontaneously. ^G-
- intrinsic properties of the reactants and products (keq)
2. the concentration of reactions and products (rtlnq)
What does spontaneously mean
It means that a rxn is favorable but does not mean that it will occur quickly.
How do enzymes effect the Transition state?
It stabilizes the transition state so that the reaction can occur more favorably. The EA is lowered by the stabilization of the transition state making it less thermodynamically favorable.
Are catalyst consumed during a rxn? If not what happens?
No, they are not consumed. They release the product and go back to being catalyst.
Enzymes
Enzymes are biologicals catalyst they increase rate of rxn by lowing EA, they do not affect ^G.
What role do catalyst play?
They stabilize TS. Lower the EA. They are kinetic in nature and do not affect thermodynamics.
Oxidization
OIL , loss of electrons which is a loss of hydrogen, gain of oxygen
Reduction
Gain of electrons, Gain of hydrogen, loss of oxygen
Catabolism
This is the break down of molecules
Anabolism
Building of materials
Bronsted Lowry Acid and Bases
Acids are proton donors, bases are proton acceptors
Lewis acids and bases
Lewis acids are electron pair acceptors, bases are electron donors
KA or KB
acid ionization and base ionization
Large KA and KB
Equates to strong acid and Base
Low KA and KB
equates to weak acid and base
