Gibbs Energy Question
Not what you're looking for?
Calculate deltaG of reaction for:
glucose+ 2 ATP ----> 2 ADP + 2 G3P
For concentrations, glucose:
5.0 mM G3P:0.019 mM ATP: 1.85 mM ADP:0.14 mM
delta G for reaction under standard conditions = -1.97 kJ, assuming the temperature is 298 K.
Do I use delta G standard + RT ln K for this reaction?
What is T in this case?

Solution Summary
The solution calculates deltaG of reaction for the given concentration.

Yes, the free energy relationship between standard state and the equilibrium product constant holds.
But lets look a bit closer at what you have. If an equilibrium is present the free energy is zero for the reaction i.e. nothing is driving it either way. I think the part that might be confusing is that in the case of non-zero free energy fot the reaction rather than a K which indicates equilibrium it is better to use the symbol Q for the equilibrium product ...
