In thermodynamics, the pressure is taken in the atm unit. Gases are at 1 bar pressure, then the incorrect option is A.
<h3>What is an electrochemical cell?</h3>
An electrochemical cell is a device that may either create electrical energy from chemical processes taking place inside it or use electrical energy given to it to promote chemical reactions taking place inside it.
In chemistry, standard pressure is usually measured in the atm rather than the bar. For electrochemical cell measurements, the standard conditions are as follows:
Gases must be at a pressure of 1 atm.
Pure liquids are required.
Solids must also be in their purest form.
The concentration of solutes is 1.0 M.
And the voltages in the cells are positive.
