Looking at the equation .look at the moles noted below

Ca(OH)_2=1mol

NH_2Cl=2mol.

CaCL_2=1mol

NH_2=2mol

H_20=2mol.

#a

There is 2 moles of NH2Cl.

Hence limiting reagent is Ca(OH)_2

#2

Moles at reactant=3

Moles at product=5

Moles left:-

\\ \sf\longmapsto 5-3=2mol

#d

\\ \sf\longmapsto pV=nRT

\\ \sf\longmapsto 1.5V=2(8.3)(27)

\\ \sf\longmapsto 1.5V=448.2

\\ \sf\longmapsto V=\dfrac{448.2}{1.5}

\\ \sf\longmapsto V=298.8mL

2 ClO2 (aq) + 2OH- (aq)→ ClO3- (aq) + ClO2- + H2O (l) was studied with the following results: Experiment [ClO2] (M) [OH-] (M) In
erica [24]

Explanation:

2 ClO2 (aq) + 2OH- (aq)→ ClO3- (aq) + ClO2- + H2O (l)

The data is given as;

Experiment [ClO2] (M) [OH-] (M) Initial Rate (M/s)

1 0.060 0.030 0.0248

2 0.020 0.030 0.00276

3 0.020 0.090 0.00828

a) Rate law is given as;

Rate = k [ClO2]^x [OH-]^y

From  experiments 2 and 3, tripling the concentration of  [OH-] also triples the rate of the reaction. This means the reaction  is first order with respect to  [OH-]

From experiments 1 and 2, when the [ClO2] decreases by a factor of 3, the rate decreases by a factor of 9. This means the reaction is second order with respect to [ClO2]

Rate =  k [ClO2]² [OH-]

b. Calculate the value of the rate constant with the proper units.

Taking experiment 1,

0.0248 = k (0.060)²(0.030)

k = 0.0248 / 0.000108

k = 229.63 M-2 s-1

c. Calculate the rate when [ClO2] = 0.100 M and [OH-] = 0.050 M.

Rate =  229.63  [ClO2]² [OH-]

Rate = 229.63 (0.100)²(0.050)

Rate = 0.1148 M/s

The standard free-energy changes for the reactions below are given.Phosphocreatine → creatine + Pi ∆ G'° = –43.0 kJ/molATP → ADP
Anton [14]

Answer:

Gibbs free-energy of the reaction = (–12.5 kJ/mol)

Explanation:

The Gibbs free-energy of a reaction predicts the spontaneity or feasibility of a given chemical reaction.

<u>Given the standard Gibbs free energy changes</u>:

Phosphocreatine → creatine + Pi,  ∆G° = –43.0 kJ/mol     ...(1)

ATP → ADP + Pi , ∆G° = –30.5 kJ/mol      ....(2)

<u>Now to calculate the Gibbs free-energy of the given chemical reaction</u>: Phosphocreatine + ADP → creatine + ATP; the <em>equation (2) is reversed</em> to give:

ADP + Pi  → ATP, ∆G° = + 30.5 kJ/mol      ...(3)

<u>Now the equation (3) and (1) are added</u>, to give:

Phosphocreatine + ADP + Pi→ creatine + ATP + Pi

⇒ Phosphocreatine + ADP → creatine + ATP  

 

Therefore, to <u>calculate the Gibbs free-energy of the reaction, the standard Gibbs free energy changes of the equations (1) and (3) are added similarly</u>:

Gibbs free-energy of the reaction: ∆G° = (–43.0 kJ/mol) + ( + 30.5 kJ/mol) = (–12.5 kJ/mol)

<u><em>Therefore, the Gibbs free-energy of the reaction </em></u><u><em>= </em></u><u><em>(–12.5 kJ/mol)</em></u>
