Interpretation:

Change in the pressure when moles of a gas are decreased is to be stated.

Concept introduction:

To study the molecules in gaseous state different laws have been given by different scientists which relates different variables to each other. Avogadro’s law relates volume of a gas with the number of moles or molecules of the same gas. According to this law when temperature and pressure of a gas is kept constant then the equal volumes of gas contains equal number of molecules of that gas. Combined gas law which is the result of Boyle’s law, Charles’s law is, Gay Lussac’s law and Avogadro’s law is written below.

$P∝T, V is constantP∝1V,T is constantV∝n, (P,T are constant)P∝n×TV$ .

Expert Solution

Answer to Problem 10E

Net value of pressure decreases with decrease in number of moles.

Explanation of Solution

Relation given by all the variables of a gas is stated as below.

$P∝n×TVP=n×T×RV$

Gas law is written below.

$PV=nRT$ …(1)

Gas law for two different gases is shown below.

$P1×V1n1×T1×R=P2×V2n2×T2×R$ …(2)

At constant volume and temperature, equation (2) is shown below.

$P1n1=P2n2$

Where,

• $P1$ is the initial pressure exerted by gas molecules.

• $P2$ .is the final pressure exerted by gas molecules.

• $n1$ is the initial number of moles of gas.

• $n2$ is final number of moles of a gas.

According to the relation given in equation (1), pressure is directly proportional to the number of moles. Pressure will be decreased with the decrease in number of moles to maintain the gas law when all other variables are kept constant.

Therefore, pressure of a gas decreases with decrease in number of moles.

Conclusion

Net value of pressure decreases with decrease in number of moles $(n)$ of a gas.
