The value of δg°\' for the conversion of dihydroxyacetone phosphate to glyceraldehyde-3-phosphate (gap) is 7.53 kj/mol. if the concentration of dihydroxyacetone phosphate at equilibrium is 1.85 mm, what is the concentration of glyceraldehyde-3-phosphate? assume a temperature of 25.0 °c. the constant r = 8.3145 j/(mol·k)

The concentration of glyceraldehyde-3-phosphate is 0.0886 nM.

Explanation:

The chemical equation for the conversion follows:

The expression for of above equation is:

Let the concentration of glyceraldehyde -3-phosphate be 'x'

Relation between standard Gibbs free energy and equilibrium constant follows:

where,

= standard Gibbs free energy = 7.53 kJ/mol = 7530 J/mol  (Conversion factor: 1kJ = 1000J)

R = Gas constant =

T = temperature =

[Glyceraldehyde-3-phosphate] = x

[Dihydroxyacetone phosphate] = 1.85 mM

Putting values in above equation, we get:

Hence, the concentration of glyceraldehyde-3-phosphate is 0.0886 nM.
