entropy, enthalpy, and
Gibbs free energies.
$200 Answer from Bioenergetics
What is ΔG = ΔH - T ΔS
Return to Game Board
$300 Question from
Bioenergetics
This is the standard free energy
change (in kJ/mole) of a reaction run
at 25°C if the equilibrium mixture
consists of 19 mM of product and
1 mM of reactant.

What is isomerization?
Return to Game Board
$500 Question from
Bioenergetics
Two reasons that hydrolysis reactions with
large, negative, standard free-energy changes
have products that are more stable than
reactants are that the products may be
stabilized by ionization and the products may
be stabilized by isomerization.
What are two other reasons for this increased
stability of products?
$500 Answer from Bioenergetics
What are:
Bond strain in reactants due to
electrostatic repulsion is relieved by
charge separation
and
Products are stabilized by resonance
