Acertain half-reaction has a standard reduction potential . an engineer proposes using this half-reaction at the cathode of a galvanic cell that must provide at least of electrical power. the cell will operate under standard conditions. note for advanced students: assume the engineer requires this half-reaction to happen at the cathode of the cell.

a. is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have?
b. is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have?

a. 1.23 V

b. No maximum

Explanation:

There is some info missing. I think this is the complete question.

A certain half-reaction has a standard reduction potential E°red = +0.13V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 1.10V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell.

The standard cell potential (E°cell) is the difference between the standard reduction potential of the cathode and the standard reduction potential of the anode.

E°cell = E°red, cat - E°red, an

If E°cell must be at least 1.10 V (E°cell > 1.10 V),

E°red, cat - E°red, an > 1.10 V

E°red, cat - 0.13V > 1.10 V

E°red, cat > 1.23 V

The minimum standard reduction potential is 1.23 V while there is no maximum standard reduction potential.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
