Use the following half-reactions to construct a voltaic cell:
cr3+(aq) + 3e−\rightarrow→ cr(s) eo = −0.73 v
ag+(aq) + e−\rightarrow→ ag(s) eo = 0.80 v
determine the balanced overall redox reaction, and calculate eocell.
3 ag(s) + cr3+(aq) \rightarrow→ 3 ag+(aq) + cr(s), eocell = −1.53 v
3 ag+(aq) + cr(s) \rightarrow→ 3 ag(s) + cr3+(aq),eocell = +3.13 v
3 ag(s) + cr3+(aq) \rightarrow → 3 ag+(aq) + cr(s), eocell = −3.13 v
ag(s) + cr3+(aq) \rightarrow→ ag+(aq) + cr(s), eocell = −1.53 v
3 ag+(aq) + cr(s) \rightarrow→ 3 ag(s) + cr3+(aq), eocell = +1.53 v
ag+(aq) + cr(s) \rightarrow→ ag(s) + cr3+(aq), eocell = +1.53 v

The correct answer is

Explanation:

We are given:

The substance having highest positive potential will always get reduced and will undergo reduction reaction. Here, silver will always undergo reduction reaction will get reduced.

Chromium will undergo oxidation reaction and will get oxidized.

The half reactions for the above cell is:

Oxidation half reaction:

Reduction half reaction:       ( × 3)

Net equation:  

Oxidation reaction occurs at anode and reduction reaction occurs at cathode.

To calculate the of the reaction, we use the equation:

Putting values in above equation, we get:

Hence, the correct answer is

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
