Calculate E° _Cell and Indicate Whether the Overall Reaction Shown

question 64

Multiple Choice

Calculate E° _cell and indicate whether the overall reaction shown is spontaneous or nonspontaneous. O₂(g) + 4H⁺(aq) + 4e^-
2H₂O(l) E° = 1.229 V
Al³⁺(aq) + 3e^-
Al(s) E° = -1.662 V
Overall reaction:
4Al(s) + 3O₂(g) + 12H⁺(aq) → 4Al³⁺(aq) + 6H₂O(l)

• A) E° _cell = -2.891 V, nonspontaneous
• B) E° _cell = -2.891 V, spontaneous
• C) E° _cell = 2.891 V, nonspontaneous
• D) E° _cell = 2.891 V, spontaneous
• E) None of these choices are correct.

Definitions:

Synapse

The junction between two neurons where information is transmitted from one neuron to another.

Agonist

A chemical or drug that binds to receptors in the brain and activates them, often mimicking the effects of naturally occurring substances.

Association Areas

Regions of the brain that integrate different types of information to perform complex functions.

Split-Brain Patients

Individuals who have undergone corpus callosotomy, a procedure that severs the corpus callosum, thereby limiting communication between the brain's two hemispheres.
