An equilibrium is not changed by a change in pressure. True OR False

1 answer:

5 0

It IS changed. When there is pressure, itll move along to the side of where there are fewer moles of gas in the reaction. Decrease in pressure causes it to shift to the side with more moles of gas. So, false, it IS in fact changed

A zinc rod is placed in 0.1 MZnSO4 solution at 298 K. Write the electrode reaction and calculate the potential of the electrode.

yanalaym [24]

Answer: The potential of electrode is -0.79 V

Explanation:

When zinc is dipped in zinc sulfate solution, the electrode formed is $Zn^{2+}(aq.)/Zn(s)$

Reduction reaction follows: $Zn^{2+}(0.1M)+2e^-\rightarrow Zn(s);(E^o_{Zn^{2+}/Zn}=-0.76V)$

To calculate the potential of electrode, we use the equation given by Nernst equation:

$E_{(Zn^{2+}/Zn)}=E^o_{(Zn^{2+}/Zn)}-\frac{0.059}{n}\log \frac{[Zn]}{[Zn^{2+}]}$

where,

$E_{cell}$ = electrode potential of the cell = ?V

$E^o_{cell}$ = standard electrode potential of the cell = -0.76 V

n = number of electrons exchanged = 2

$[Zn]=1M$ (concentration of pure solids are taken as 1)

$[Zn^{2+}]=0.1M$

Putting values in above equation, we get:

$E_{cell}=-0.76-\frac{0.059}{2}\times \log(\frac{1}{0.1})\\\\E_{cell}=-0.79V$

Hence, the potential of electrode is -0.79 V

kati45 [8]

Answer: The law that illustrates this is Boyle's Law

Explanation:

Boyle's law: This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

Mathematically,

$P\propto \frac{1}{V}$ (at constant temperature and number of moles)

Charles' law: This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

Mathematically,

$V\propto T$ (at constant pressure and number of moles)

Avogadro's law: This law states that volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature.

Mathematically,

$V\propto n$ (at constant pressure and temperature)

So, when the volume of the air in the gun decreases, the pressure is increased. The inverse relationship between the volume and pressure of the gas is very well illustrated by Boyle's Law.

Hence, the law that illustrates this is Boyle's Law
