A solution is a mixture (solvent + solute) of 2 or more elements, for example chocolate milk.

A solvent is the base of the solution which dissovles a solute, for example milk.

A solute is what is dossolved by the solvent, for example chocolate powder.

Solvent - the liquid in which a solute is dissolved to form a solution

Solution - a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent)

Solute - the dissolved substance in a solution

Answer:

For A: The free energy change of the reaction is -5339.76 J/mol

For B: The units of free energy change of the reaction are kJ/mol

For C: The forward reaction is favorable and reverse reaction is unfavorable.

Explanation:

For the given chemical reaction:

$DHAP\rightleftharpoons G_3P$

For A:

Relation between standard Gibbs free energy and equilibrium constant follows:

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

To calculate the free energy change, we use the equation:

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

Or,

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

where,

$\Delta G$ = Free energy change

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

$T^o$ = standard temperature = $25^oC=[273+25]K=298K$

T = temperature of the cell = $37^oC=[273+37]K=310K$

$K_[eq}$ = equilibrium constant = $5.4\times 10^{-2}$

Q = reaction coefficient = $\frac{[G_3P]}{[DHAP]}$

$[G_3P]$ = 0.06 M

[DHAP] = 0.125 M

Putting values in above equation, we get:

$\Delta G=[-(8.314J/mol.K\times 298K\times \ln (5.4\times 10^{-2}))]+[(8.314J/mol.K\times 310K\times \ln (\frac{0.06}{0.125}))]\\\\\Delta G=-[-7231.46]+[-1891.7]=-5339.76J/mol$

Hence, the free energy change of the reaction is -5339.76 J/mol

For B:

Converting the free energy change of the reaction into kilojoules, we use the conversion factor:

1 kJ = 1000 J

So, $-5339.76J/mol\times \frac{1kJ}{1000J}=-5.34kJ/mol$

Hence, the units of free energy change of the reaction are kJ/mol

For C:

For the reaction to be spontaneous, the Gibbs free energy of the reaction must come out to be negative. But, from the above calculation, the Gibbs free energy of the reaction is positive. Thus, the reaction is non-spontaneous.

As, the free energy change of the reaction is negative.

Hence, the forward reaction is favorable and reverse reaction is unfavorable.

Avogadro's law relates the volume of a gas to the number of moles of gas

GarryVolchara [31]

The volume would be three times the original volume is the correct answer.

<h3>What change occur in the volume of product?</h3>

The volume would be three times the original volume because a reaction produced 3 moles of gas from 1 mole of gaseous reactants. The ratio between reactants and products are 1:3 which shows that three times increase occur in the volume between reactant and products.

So we can conclude that the volume would be three times the original volume is the correct answer.

Can someone please answer this?

Amanda [17]

Answer:-

0.229 L

Explanation:-

Molar mass of AgBr = 107.87 x 1 + 79.9 x 1

=187.77 grams mol-1

Mass of AgBr = 150 grams

Number of moles of AgBr = 150 grams / 187.77 gram mol-1

= 0.8 mol

The balanced chemical equation is

NaBr (aq) + AgNO3 (aq)--> AgBr(s) + NaNO3(aq)

From the equation we can see that

1 mol of AgBr is produced from 1 mol of AgNO3.

∴ 0.8 mol of AgBr is produced from 1 x 0.8 / 1 = 0.8 mol of AgNO3.

Strength of AgNO3 = 3.5 M

Volume of AgNO3 required = Number of moles / strength

= 0.8 moles / 3.5

=0.229 L
