the triangleG and triangleG0! both refer to the free energy change in the steady state reaction. steady state means that the concentrations of substrates and products are fixed or constant. all of the following statements about triangleG and triangleG0! are true EXCEPT?
a. triangleG refers to a specific reaction with fixed(constant) concentrations of substrate and products
b. triangleG0! refers to a reaction at pH=7 and 25 degrees centigrade
c. triangleG0! for a specific reactions can have many values
d. triangleG and triangleG0! can both have positive or negative values
e. triangleG0! refers to a reaction with the concentrations of substrates and products, except hydrogen ion, fixed at one molar concentration
