A red shift in the spectrum of the light from an object indicates the object is moving ____ you.

jek_recluse [69]

Away from you. This is known as the Doppler affect. It basically states that if an object is moving away from you the streching of the wave causes a red shift and if the object is moving towards you the compression of the waves causes a blue shift.

For the aqueous reaction dihydroxyacetone phosphate is the reactant and glyceraldehyde 3 phosphate is the product. dihydroxyacet

lbvjy [14]

Answer: The Gibbs free energy of the reaction is -445 J/mol.

Explanation:

The chemical equation for the conversion follows:

$\text{Dihydroxyacetone phosphate}\rightleftharpoons \text{Glyceraldehyde-3-phosphate}$

The expression for $K_{eq}$ of above equation is:

$K_{eq}=\frac{\text{[Glyceraldehyde-3-phosphate]}}{\text{[Dihydroxyacetone phosphate]}}$

We are given:

[Glyceraldehyde-3-phosphate] = 0.00400 M

[Dihydroxyacetone phosphate] = 0.100 M

Putting values in above equation, we get:

$K_{eq}=\frac{0.004}{0.100}=0.04$

Relation between standard Gibbs free energy and equilibrium constant follows:

$\Delta G=\Delta G^o+RT\ln K_1$

where,

$\Delta G^o$ = Standard Gibbs free energy = 7.53 kJ/mol = 7530 J/mol (Conversion factor: 1kJ = 1000J)

R = Gas constant = $8.314J/K mol$

T = temperature = 298 K

Putting values in above equation, we get:

$\Delta G=7530J/mol+(8.3145J/Kmol)\times 298K\times \ln (0.04)\\\\\Delta G=-445J/mol$

Hence, the Gibbs free energy of the reaction is -445 J/mol.
