During a laboratory experiment, you discover that an enzyme-catalyzed reaction has a ΔG = -6 kcal/mole when the enzyme concentration is 1 microgram/ml. If we decrease the amount of enzyme to 0.5 micrograms/ml what will the ΔG be?
a.-3 kcal/mole
b. +3 kcal/mole
c. -6 kcal/mole
d. -12 kcal/mole
e. It is not possible to calculate the answer with the information given.
Option e is correct
Taking into consideration Gibbs equation
ΔG=−RTlnK.
R (Universal Gas Constant) = 8.314 J Mol-1 K-1
T = Temperature Unknown ( Assuming it at 298)
K = Initial Concentration = 1 (ln(1) = 0)
Substituring the values we get 0.
