Answer:
ΔS = -661.0J/mol is the entropy change for the system
ΔS = -842J/mol.K is the entropy change for the surroundings
Explanation:
From the relationship between ΔG, T, ΔH and ΔS,
Mathematically, ΔG = ΔH - TΔS
TΔS = ΔH - ΔS
ΔS = ΔH - ΔS / T
but ΔG = -54 kJ/mol, ΔH = -251 kJ/mol and T = 25 °C (298 K)
plugging into the equation,
ΔS = -251 kJ/mol - ( -54 kJ/mol) / 298
ΔS = -0.6610KJ/mol or in J.mol
ΔS = -661.0J/mol is the entropy change for the system
- For entropy change for the surroundings = ΔS = ΔH/T
- ΔS = -0.84KJ/mol.K or -842J/mol.K is the entropy change for the surroundings
Answer:
In the presence of a base, blue litmus paper will turn red........
Answer:
The ratio of the products to reactants remains caonstant over time
Explanation:
Answer:
A base that forms K⁺ and OH⁻ ions.
Explanation:
The KOH is an Arrhenius base.
A is <em>wrong</em>. A base does not form H⁺ ions.
B is <em>wrong</em>. A metal hydroxide forms K⁺ ions, not KO⁻ ions.
D is <em>wrong</em>. The metal forms K⁺ ions, KO⁻ ions.
