Triose phosphate isomerase converts dihydroxyacetone phosphate (DHAP)to glyceraldehyde (G3P) in reversible reaction. At 298 K and pH 7 ,the equilibrium mixture contain 40mM DHAP and 4mM G3P .Assume that the reaction started with 44 mM DHAP and no G3P .The standard free energy in Kj/mol for formation of G3P is__________...

R=8.314j/mol.k

I'm getting 5.7

But the ans key is 2.5
So lemme know why the is such a variation ...
