Final answer:
If one were to double the amount of enzyme in a reaction with an initial ΔG of -5 kcal/mole, the ΔG value would remain the same.
Step-by-step explanation:
The change in free energy (ΔG) of a reaction can be calculated using the equation ΔG˚ = -RT ln K, where ∆G˚ is the standard free energy change, R is the gas constant, T is the temperature in Kelvin, and K is the equilibrium constant.
If the initial ΔG is -5 kcal/mole and the amount of enzyme is doubled, the ΔG value remains the same.
