Which of the following is a correct method to calculate the EMF of a galvanic cell? + b) Standard EMF of the cell = – c) E°cell = E°cathode – E°anode d) Standard EMF of the cell = +

Correct Answer: Standard reduction potential of the reduction half reaction
The correct methods to calculate the EMF of a galvanic cell are: Standard EMF of the cell = – . Standard EMF of the cell = + . E°cell = E°cathode – E°anode. Standard EMF of the cell = – .

Consider the following statements.
1. Galvanic cell converts chemical energy into electrical energy.
2. In a galvanic cell, the electron flow from anode to cathode through the external circuit.
3. Galvanic cell converts metal from its elemental state to the combined state.
Which of the statement(s) given above is/are correct?

Choose the right option among the alternatives – A thyristor goes into full conduction in its forward direction when anode/cathode/gate is positive with respect to its anode/cathode/gate and a turn-on voltage or current signal in the form of a pulse is given to its anode/ cathode/gate.

Assertion (A) For a galvanic cell, oxidation takes place at anode and reduction at cathode.
Reason (R) Electrons in the external circuit move from anode to cathode

What is the standard reduction potential of the cathode of a galvanic cell if the standard EMF of the cell and the standard reduction potential of the anode are 2.71 and -2.37 respectively?

What is the EMF of a galvanic cell if E°cathode = 0.80 volts and E°anode = -0.76 volts?

An electrochemical cell generally consists of a cathode and an anode. Which of the following statements is correct with respect to the cathode?

How do electrons flow in the galvanic cell from anode to cathode?

Potential of earth is – 50 V. If the potential difference between anode and cathode (earthed) is measured as 150 V, actual voltage on anode is __________

What is the EMF of a galvanic cell if the standard oxidation potential of the oxidation half-reaction is 0.64 volts and the standard reduction potential of the reduction half-reaction is 0.48 volts?

What is the EMF of a galvanic cell if the standard reduction potential of the reduction half-reaction is -0.38 volts and the standard reduction potential of the oxidation half-reaction is 0.52 volts?
