Electrochemistry part 2

What does the nernst equation relate to in electrochemistry?

• Rate of reaction

• Equilibrium constant

• Electrode potential

The nernst equation is used to calculate:

• pH of solution

• Standard electrode potential

• Concentration of ion

• Cell potential under non- standard condition

Which of the following included in the nernst equation?

• Temperature

• Pressure

• Catalyst

• Viscosity

The nernst equation introduce the dependency of the electrode potential on

• Pressure only

• Temperature only

• Ion concentration

• Both temperature and ion concentration

For a half-cell reaction Zn²⁺ + 2e⁻ → Zn(s), what would be the effect on the electrode potential if the concentration of Zn²⁺ is decreased?

f the cell potential is zero, what does the Nernst equation tell us about the reaction?

• The reactants and products are in equilibrium.

• The reaction is very rapid.

• There are no ions present.

• It is operating under non-standard conditions
