An enzyme-catalyzed reaction has a ∆G of -20 kcal/mol under standard conditions. What will be the ∆G for the reaction if the amount of enzyme is doubled?
A) -40 kcal/mol
B) -20 kcal/mol
C) -10 kcal/mol
D) +20 kcal/mol

Question

Quizplus · Accepted Answer

The ∆G (change in Gibbs free energy) of a reaction is a thermodynamic property that depends on the initial and final states of the reaction, not on the pathway or mechanism, including the amount of enzyme present. Therefore, doubling the amount of enzyme does not change the ∆G of the reaction.
