The answer is "Choice A and Choice B"
Explanation:
The Zero-Order reactions are usually found if a substrate, like a surface or even a catalyst, is penetrated also by reactants. Its success rate doesn't depend mostly on the amounts of the various reaction in this reaction.
Let the Rate = k
As doesn't depend on reaction rate, a higher reaction rate does not intensify the reaction.
By the rate the created based and the reaction rate is about the same.
The concentration in /mmolL of the chemist's silver(I) nitrate solution is 0.01047 mmoles/litre.
Explanation:
Data given:
Number of moles of AgNO3 in micro mole 4.7102micromol.
The concentration is supposed to be in mmol so the micromole will be converted to milimole.
So, 1 micromole = 0.001 millimole
hence, 4.712micromole will be 0.004712 millimole.
Volume is given as 450ml which is converted into L
to convert ml into L it is divided by 1000
so 0.45 L is the volume.
Molarity or concerntration is calculated by the formula,
molarity =
putting the values in the formula:
molarity =
= 0.01047 mmoles/litre is the molarity of AgNO3 solution in 450 ml of solution.
Answer:
I. Kindly, see the attached image.
II. The reaction is exothermic.
III. - 51.88 kJ/mol.
IV. The reaction is spontaneous.
Explanation:
I. Draw a possible potential energy diagram of the reaction. Label the enthalpy of the reaction.
- Since the sign of ΔH is negative, the reaction is exothermic reaction.
In an exothermic reaction, the energy of the reactants is higher than that of the products.
<u><em>Kindly see the attached image to show you the potential energy diagram of the reaction.</em></u>
<em>II. Is the reaction endothermic or exothermic? Explain your answer.</em>
- The reaction is exothermic reaction.
- The sign of ΔH indicates wither the reaction is endothermic or exothermic one:
If the sign is positive, the reaction is endothermic.
If the sign is negative, the reaction is exothermic.
Herein, <em>ΔH = - 33.1 kJ/mol, </em>so the reaction is exothermic.
<em>III. What is the Gibbs free energy of the reaction at 25°C? </em>
∵ ΔG = ΔH - TΔS.
Where, ΔG is the Gibbs free energy change (J/mol).
ΔH is the enthalpy change (ΔH = - 33.1 kJ/mol).
T is the temperature (T = 25°C + 273 = 298 K).
ΔS is the entorpy change (ΔS = 63.02 J/mol.K = 0.06302 J/mol.K).
<em>∴ ΔG = ΔH - TΔS</em> = (- 33.1 kJ/mol) - (298 K)(0.06302 J/mol.K) = <em>- 51.88 kJ/mol.</em>
IV. Is the reaction spontaneous or nonspontaneous at 25°C?
The sign of ΔG indicates the spontaneity of the reaction:
If ΔG < 0, the reaction is spontaneous.
If ΔG = 0, the reaction is at equilibrium.
If ΔG > 0, the reaction is nonspontaneous.
Herein, <em>ΔG = - 51.88 kJ/mol, </em>so the reaction is spontaneous.
