Consider the following phosphate transfer reaction that is
exergonic under standard conditions:
A~P + B → B~P + A
The standard free energy for A~P → A + Pi is -25.6 kj/mol
What can be predicted for the standard free energy of: B + Pi
--> B~P ?
a. -25.6 kj/mol
b. -12.0 kj/mol
c. +12.0 kj/mol
d. +25.6 kj/mol
e. None of the above
Homework Answers
d. +25.6 kj/mol
The standard free energy change on the left hand side reaction is -25.6 kj/mol.
So, to balance the chemical reaction the right hand side standard free energy would be +25.6 kj/mol as no other intermediary reactions are involved.
