![Q.43 Triose phosphate isomerase converts dihydroxyacetone phosphate (DHAP) to glyceraldehyde-3-phosphate (G-3-P) in a reversible reaction. At 298 K and pH 7.0, the equilibrium mixture contains 40 mM DHAP and 4 mM G-3-P. Assume that the reaction started with 44 mM DHAP and no G-3-P. The standard free-energy change in kJ/mol for the formation of G-3-P [R = 8.315 J/mol·K] is ______.](https://www.letstalkacademy.com/wp-content/uploads/2026/01/slide_43-1.jpg)
