<u>Answer:</u> The equilibrium constant of the reaction is 0.0526 and standard Gibbs free energy of the reaction is -7.296 kJ/mol

<u>Explanation:</u>

For the given chemical equation:

\text{Glucose-6-phosphate}\rightleftharpoons \text{Glucose-1-phosphate}

The expression of K_{eq} for above equation follows:

K_{eq}=\frac{[\text{Glucose-1-phosphate}]}{[\text{Glucose-6-phosphate}]}

We are given:

[\text{Glucose-1-phosphate}]=0.01M

[\text{Glucose-6-phosphate}]=0.19M

Putting values in above expression, we get:

K_{eq}=\frac{0.01}{0.19}=0.0526

The equation used to calculate standard Gibbs free energy of the reaction follows:

\Delta G^o=+RT\ln K_{eq}

where,

\Delta G^o = Standard Gibbs free energy

R = Gas constant = 8.314 J/K mol

T = Temperature = 25^oC=[25+273]K=298K

K_{eq} = Equilibrium constant of the reaction = 0.0526

Putting values in above equation, we get:

\Delta G^o=8.314J/K.mol\times 298K\times \ln (0.0526)\\\\\Delta G^o=-7296.5J/mol=7.296kJ/mol

Hence, the equilibrium constant of the reaction is 0.0526 and standard Gibbs free energy of the reaction is -7.296 kJ/mol

How can one kg of iron melt more ice than 1 kg lead at 100 °C
Vanyuwa [196]

Answer:

Due to the specific heat capacity of iron, 0.444 J/(g·°C), is more than the specific heat capacity for lead, 0.160 J/(g·°C)

Explanation:

The given parameters are;

The metals provided to melt the ice and their temperature includes;

One kg (1000 g) of iron;

Specific heat capacity = 0.444 J/(g·°C)

Temperature = 100°C

1 kg (1000 g) of lead

Specific heat capacity = 0.160 J/(g·°C)

Temperature = 100°C

Therefore, the heat provided to the ice of mass m, and latent heat of 334 J/g at 0°C by the metals are as follows;

For iron, we have;

ΔQ = Mass × Specific heat capacity × Temperature change

ΔQ_{iron} = Heat obtained from the iron by the ice

ΔQ_{iron} = 0.444 m × 1000 × (100 - 0) = 44400 J

Heat absorbed by the ice for melting, H_l = Heat obtained from the iron

∴ Heat absorbed by the ice for melting, H_l = Mass of ice × Latent heat of ice

H_l = Mass of ice × 334 J/g = 44400 J

Mass of ice melted by the iron = 44400 J/334 (J/g) ≈ 132.9 g

Mass of ice melted by the iron ≈ 132.9 g

For lead, we have;

ΔQ = Mass × Specific heat capacity × Temperature change

ΔQ_{lead} = Heat obtained from the iron by the ice

ΔQ_{lead} = 0.160 m × 1000 × (100 - 0) = 16000 J

Heat absorbed by the ice for melting, H_l = Heat obtained from the iron

∴ Heat absorbed by the ice for melting, H_l = Mass of ice × Latent heat of ice

H_l = Mass of ice × 334 J/g = 16000 J

Mass of ice melted by the lead = 16000 J/334 (J/g) ≈ 47.9 g

Mass of ice melted by the lead ≈ 47.9 g

Therefore, mass of  ice melted by the iron, approximately 132.9 g, is more than mass of ice melted by the lead, approximately 47.9 g.
