Answer: equilibrium constant.
- A the rate constant
- B equilibrium constant
- C the solution pH
- D the molar mass
Correct answer: B. equilibrium constant
Explanation: This links the standard cell potential to the equilibrium constant Kc of the cell reaction.
In a Daniell cell, electrons flow externally from the zinc anode (oxidation) through the voltmeter to the copper cathode (reduction), while the salt bridge completes the circuit.
