Refer to the galvanic cell below (the contents of each half-cell are written beneath each compartment):

0.10 M MnO4                           0.40 M Cr3+
0.20 M Mn2+                             0.30 M Cr2O72–
0.010 M H+                              0.010 M H+
The standard reduction potentials are as follows:
MnO4 + 8H+ + 5e→ Mn2+ + 4H2O, E° = 1.51 V
Cr2O72– + 14H+ + 6e→ 2Cr3+ + 7H2O, E° = 1.33 V

In which direction do electrons flow in the external circuit?

Reference: 18-3


left to right
right to left
no current flows; the cell is at equilibrium
no current flows; the cell is not at equilibrium
None of these are correct.

YES! Correct, THANKS for helping me on my review

 

Did you know?

It is believed that the Incas used anesthesia. Evidence supports the theory that shamans chewed cocoa leaves and drilled holes into the heads of patients (letting evil spirits escape), spitting into the wounds they made. The mixture of cocaine, saliva, and resin numbed the site enough to allow hours of drilling.

Did you know?

The modern decimal position system was the invention of the Hindus (around 800 AD), involving the placing of numerals to indicate their value (units, tens, hundreds, and so on).

Did you know?

Cyanide works by making the human body unable to use oxygen.

Did you know?

Many of the drugs used by neuroscientists are derived from toxic plants and venomous animals (such as snakes, spiders, snails, and puffer fish).

Did you know?

There used to be a metric calendar, as well as metric clocks. The metric calendar, or "French Republican Calendar" divided the year into 12 months, but each month was divided into three 10-day weeks. Each day had 10 decimal hours. Each hour had 100 decimal minutes. Due to lack of popularity, the metric clocks and calendars were ended in 1795, three years after they had been first marketed.
