Ag' for the isomerization reaction glucose-1-phosphate (gip) $ glucose-6-phosphate (g6p) is -7.1 kj/mol. calculate the equilibrium ratio of [g1p] to (g6p) at 25°c. read this carefully to make sure you solve for the correct ratio! show work! [g1p][g6p] =

The ratio [G1P]/[G6P] = 5.7 . 10⁻².

Explanation:

Let us consider the reaction G1P ⇄ G6P, with ΔG° = -7.1 kJ/mol. According to Hess's Law, we can write the inverse reaction, and Gibbs free energy would have an opposite sign.

G6P ⇄ G1P        ΔG° = 7.1 kJ/mol

This is the reaction for which we want to find the equilibrium constant (the equilibrium ratio of [G1P] to [G6P]):

The equilibrium constant and Gibbs free energy are related by the following expression:

where,

R is the ideal gas constant (8.314 . 10⁻3 kJ/mol.K)

T is the absolute temperature (in kelvins)

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
