1)
An electrolytic cell:
All of the above
Has a non-spontaneous chemical reaction
Has a positively charged anode
Requires application of a negative potential to make the reaction occur
None of the above
2)
If we pass a current of 10.0 Amperes through a solution for 1 hour, how many moles of electrons are used?
10 x 1
10 x 1 x 3600 / 96487
10 x 1 x 3600 x 96487
10 x 1 x 3600
none of the above
3)
The REDOX reaction Zn(s) + Cu²⁺(aq) = Zn²⁺(aq) + Cu(s) has E₀ = +1.10 V. The standard free energy for this reaction can be calculated as.....
DG₀ = 96487 (1.10) J/mol
DG₀ = 2 (96487) (1.10) J/mol
DG₀ = - 3 (96487) (1.10) J/mol
DG₀ = - 2 (96487) (1.10) J/mol
DG₀ = - 96487 (1.10) J/mol
4)
The fuel cell we discussed in class forms the following product.
H₂SO₄
H₂S
H₂
O₂
H₂O
5)
The electric charge or electrode deposition of one gram equivalent of a substance is .....
96,500 coulombs per second
charge on one mole of electrons
one ampere for one second
one ampere for one hour
