Third choice because the others make no sense
In the given situation, the gas is heated under constant volume. As energy is supplied to the system in the form of heat, the frequency of collision between the gas particles increases. This increases the temperature of the gas consequently bringing about a decrease in pressure.
Based on the ideal gas law:
PV = nRT
Here, P/T = nR/V
If P1, T1 and P2, T2 are the pressure and temperature values before and after heating respectively, then since nR/V is a constant in this case, we have
P1/T1 = P2/T2 which is the Gay-Lussac's law.
Balanced equation
2 Al(s) + 3 CuSo4(aq) = 3 Cu(s) + Al2(SO4)3(aq)
Reaction type : single replacement
<h3>Further explanation</h3>
Given
Al(s) ± CuSO4(aq)
Required
Balanced equation
Reaction type
Solution
Reaction
Al(s) + CuSo4(aq) = Cu(s) + Al2(SO4)3(aq)
- Give a coefficient (the most complex compound=1)
aAl(s) + bCuSO4(aq) = cCu(s) + Al2(SO4)3(aq)
Al, left = a, right = 2⇒a=2
S, left = b, right = 3⇒b=3
Cu, left = b, right = c⇒c=b=3
The equation becomes :
<em>2 Al(s) + 3 CuSo4(aq) = 3 Cu(s) + Al2(SO4)3(aq)</em>

A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
Not all of these reactions can occur. We can use the activity series(voltaic series). In this reaction, Al more reactive than Cu, so the reaction can occur.
Overvoltage influence the products in the electrolysis of aqueous salts by affecting the solvation effects, polarization of electrode, and also affect the formation of gaseous products.
<h3>What is electrolysis? </h3>
It is defined as a process which leads to the chemical change when an electric current is allow to pass through an electrolyte.
During the electrolysis process,the positively charged electrode gains the electrons and undergoes the reduction process while the negatively charged electrode loses the electrons , undergoes oxidation.
When two half reaction are possible at an electrode, one with the other which is more positive electrode potential occur. For the gases to be produced at electrodes, an additional voltage is required. This is termed as overvoltage.
The overvoltage affects the solvation effects, polarization of electrode, and also affect the formation of gaseous products.
