Question 1

A common car battery consists of six identical cells, each of which carries out the reaction:
Pb + PbO2 + 2HSO4– + 2H+ 2PbSO4 + 2H2O
The value of E° for such a cell is 2.043 V. Calculate ΔG° at 25 °C for the reaction.

◦ –197.1 kJ
◦ –98.56 kJ
◦ –394.2 kJ
◦ –788.5 kJ
◦ –591.4 kJ

Question 2

A concentration cell is constructed using two metal (M) electrodes with M2+ concentrations of 0.10 M and 1.00 10–5M in the two half-cells. Determine the reduction potential of M2+ given that the potential of the cell at 25°C is 0.118 V.

◦ 0 V
◦ +0.118 V
◦ –0.118 V
◦ 0.237 V
◦ Cannot be determined with the information given.

Did you know?

Asthma attacks and symptoms usually get started by specific triggers (such as viruses, allergies, gases, and air particles). You should talk to your doctor about these triggers and find ways to avoid or get rid of them.

Did you know?

Elderly adults are at greatest risk of stroke and myocardial infarction and have the most to gain from prophylaxis. Patients ages 60 to 80 years with blood pressures above 160/90 mm Hg should benefit from antihypertensive treatment.

Did you know?

Hippocrates noted that blood separates into four differently colored liquids when removed from the body and examined: a pure red liquid mixed with white liquid material with a yellow-colored froth at the top and a black substance that settles underneath; he named these the four humors (for blood, phlegm, yellow bile, and black bile).

Did you know?

There are over 65,000 known species of protozoa. About 10,000 species are parasitic.

Did you know?

Vaccines cause herd immunity. If the majority of people in a community have been vaccinated against a disease, an unvaccinated person is less likely to get the disease since others are less likely to become sick from it and spread the disease.
