Consider a gas at tmperature T occupying a volume V consisting of a mixture of two gases having. `N_a & N_b` atoms of masses `m_a & m_b` respsectively.
Give an expression for the total pressure exerted by the gas

A

`((N_(a)+N_(b))kT)/V`

B

`(1.5(N_(a)+N_(b))kT)/V`

C

`((N_(a)+N_(b))RT)/V`

D

none

Text Solution

Verified by Experts

The correct Answer is:
A
`P=(nRT)/V`,where n=number of moles of all gases
`:.n=(N_(a)+N_(b))/N,` N=Avogadro number
`P=((N_(a)+N_(b)))/N (RT)/V=(N_(a)+N_(b))/V R/NT=((N_(a)+N_(b))kT)/V`

Consider a gas at temperature T occupying a volume V consisting of a mixture of two gases having N_(a) & N_(b) atoms of masses m_(a) & m_(b) respectively. Suppose that N_(a)=N_(b) the different atoms combine at constant volume to form molecules of mass m_(a)+m_(b) . Once the temperature returns to its original value, what would be the ratio of the pressure after combination to the pressure before?

A closed vessel at temperature T contains a mixture of two diatomic gases A and B. Atomic mass of A is 16 times that of B and mass of gas A contained in the vessel is 2 times that of B. which of the following statements are correct?

Two gases A and B having the same pressure P, volume V and temperature T are mixed. If mixture has volume and temperature as V and T respectively, then the pressure of the mixture will be

A container encloses 1.5 mol of an ideal gas that has molar mass M, and 0.50 mol of a second ideal gas that has molar mass M, 3.0M What fraction of the total pressure on the container wall is attributable to the second gas? (The kinetic theory explanation of pressure leads to the experimentally discovered law of partial pressures for a mixture of gases that do not react chemically: The total pressure exerted by the mixture is equal to the sum of the pressures that the several gases would exert separately if each were to occupy the vessel alone. The molecule-vessel collisions of one type would not be altered by the presence of another type.)

Two gases A and B each at temperature T. Pressure P and volume V, are mixed. If the mixture be at the same temperature T and its volume also be V, then what should be its pressure ? Explain.

A gaseous mixture enclosed in a vessel of volume V consists of one gram mole of gas A with gamma = (C_(P))/(C_(V)) = (5)/(3) an another gas B with gamma = (7)/(5) at a certain temperature T . The gram molecular weights of the gases A and B are 4 and 32 respectively. The gases A and B do not react with each other and are assumed to be ideal. The gaseous mixture follows the equation PV^(19//13) = constant , in adiabatic process. Find the number of gram moles of the gas B in the gaseous mixture.

Two gases A and B having the same temperature T, same pressure P and same volume V are mixed. If the mixture is at the same temperature and occupies a volume V. The pressure of the mixture is
