1.
E°cell for Zn | Zn2+ || Cu2+ | Cu is:
-1.10 V
+0.42 V
+1.10 V
-0.42 V
2.
Why is platinum used in the Fe3+/Fe2+ half-cell?
It is inert and conducts electricity
It catalyses the reaction
It is oxidised easily
It provides Fe ions
3.
Why is KMnO4 titration acidified with H2SO4, not HCl?
HCl is too weak
H2SO4 is an indicator
HCl gives a precipitate
MnO4- would oxidise Cl- to Cl2
4.
What is the only product of a hydrogen fuel cell?
CO2
H2O
H2O2
OH-
5.
A positive E°cell means the reaction may not occur because:
ΔStotal is negative
It is endothermic
The activation energy may be high
K is less than 1
6.
How many moles of Fe2+ react with 0.0020 mol MnO4-?
0.010
0.0020
0.0004
0.0040
7.
Which statement best describes Oxidation?
Loss of electrons, or an increase in oxidation number.
H2 gas at 100 kPa bubbled over platinum in 1.00 mol dm-3 H+ at 298 K, assigned E° = 0.00 V.
Gain of electrons, or a decrease in oxidation number.
The emf of a half-cell measured against the standard hydrogen electrode under standard conditions (298 K, 100 kPa, 1.00 mol dm-3).
8.
Which statement best describes E°cell?
Gain of electrons, or a decrease in oxidation number.
The standard emf of a cell: E°right - E°left (reduction half-cell minus oxidation half-cell).
The emf of a half-cell measured against the standard hydrogen electrode under standard conditions (298 K, 100 kPa, 1.00 mol dm-3).
A cell that converts chemical energy of a continuously supplied fuel and oxidant directly into electrical energy.
9.
Which statement best describes Disproportionation?
A reaction in which the same element is both oxidised and reduced.
Loss of electrons, or an increase in oxidation number.
A connection (e.g. filter paper soaked in KNO3) that allows ions to move between half-cells, completing the circuit.
The emf of a half-cell measured against the standard hydrogen electrode under standard conditions (298 K, 100 kPa, 1.00 mol dm-3).
10.
Which statement best describes Standard hydrogen electrode?
The standard emf of a cell: E°right - E°left (reduction half-cell minus oxidation half-cell).
The emf of a half-cell measured against the standard hydrogen electrode under standard conditions (298 K, 100 kPa, 1.00 mol dm-3).
A species that accepts electrons and is itself reduced.
H2 gas at 100 kPa bubbled over platinum in 1.00 mol dm-3 H+ at 298 K, assigned E° = 0.00 V.
