Q. In electrochemistry, what does the Nernst equation relate to?
A.
Concentration and pressure
B.
Temperature and volume
C.
Cell potential and concentration
D.
Mass and energy
Solution
The Nernst equation relates the cell potential to the concentrations of the reactants and products, allowing for calculation of voltage under non-standard conditions.
Correct Answer:
C
— Cell potential and concentration
Q. Which principle explains the shift in equilibrium when a stress is applied to a system?
A.
Le Chatelier's Principle
B.
Hess's Law
C.
Raoult's Law
D.
Gibbs Free Energy
Solution
Le Chatelier's Principle states that if a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change.
