Answer:
1. The correct option is;
c. maintains charge balance in the cell
2. The correct option is;
c. +3.272 V
Explanation:
The aqueous solution in a galvanic cell is the electrolyte which is a ionic solution containing that permits the transfer of ions between the separated compartment of the galvanic cell such that the overall system is electrically neutral
Therefore, the aqueous solution maintains the charge balance in the cell
2. Here we have;
B₂ + 2e⁻ → 2B⁻ Ecell = 0.662 V
A⁺ + 1e⁻ → A Ecell = -1.305 V
Hence for the overall reaction, we have;
2A + B₂ → 2AB gives;
(0.662) - 2×(-1.305) = +3.272 V.

Answer:
The rate law is rate = k[NO][O₃]
Option E) is the right answer.
Explanation:
Hi there!
For this generic reaction:
A + B → products
the rate law will be:
rate = k[A]ⁿ[B]ᵃ
this reaction is n-order in A and a-order in B. The overall reaction is the sum of the orders of each reactant, in this case:
Overall order of the reaction = n + a
In our problem, we know that the reaction is first order in O₃ and second order overall. Then:
Overall order of the reaction = Order in NO + Order in O₃
2 = n + 1
2 - 1 = n
n = 1
Then, the reaction is first order in NO and first order in O₃.
The rate law will be:
rate = k[NO][O₃]
The right answer is the option E).
