The cell notation for the given voltaic cell is as follows
Al(s) | Al³⁺(aq) || Cr³⁺ (aq) | Cr(s)
<h3>What is a voltaic cell?</h3>The device in which electrons are transferred through an external source is known as a voltaic cell.
The electron flow of a Voltaic cell allows redox reactions to produce energy in the form of electricity.
It converts the energy of spontaneous redox reaction into electrical energy
An anode, a cathode, and a salt bridge are all parts of a voltaic cell's setup. The salt bridge serves to neutralize the system.
To write the cell notation, identify the oxidation and reduction reactions.
At the anode, oxidation takes place
At the cathode, reduction takes place
While writing cell notation, the anode is written on the left, and the cathode is written on the right
A single vertical line differentiates between the phases and a double vertical line represents the salt bridge.
Now, write the cell notation of the given Voltaic cell
Al(s) | Al³⁺(aq) || Cr³⁺ (aq) | Cr(s)

Answer:
Choice d. No effect will be observed as long as other factors (temperature, in particular) are unchanged.
Explanation:
The equilibrium constant of a reaction does not depend on the pressure. For this particular reaction, the equilibrium quotient is:
.
Note that the two sides of this balanced equation contain an equal number of gaseous particles. Indeed, both and
will increase if the pressure is increased through compression. However, because
and
have the same coefficients in the equation, their concentrations are raised to the same power in the equilibrium quotient
.
As a result, the increase in pressure will have no impact on the value of . If the system was already at equilibrium, it will continue to be at an equilibrium even after the change to its pressure. Therefore, no overall effect on the equilibrium position should be visible.
