Question

need help please!!

(1) Is a mixture of ideal gases also an ideal gas? (Yes/No) (2) Is the temperature of an ideal gas mixture equal to the sum of the temperatures of each individual gas in the mixture? (Yes/No) (3) A mixture of several gases has identical masses for each component. Will all the mole fractions be identical? (Yes/No) (4) An insulated rigid tank is divided into two compartments by a partition. One compartment contains 0.5 kmol of CO2 at 27°C and 200 kPa, and the other compartment contains 7.5 kmol of H2 gas at 40°C and 400 kPa. Now the partition is removed, and the two gases are allowed to mix. Determine (a) the mixture temperature and (b) the mixture pressure after equilibrium has been established. Assume constant specific heats at room temperature for both gases.

Explanation / Answer

1. Yes, the mixture of an ideal gas is also an ideal gas.

2. No.

3.No, mass fraction will be identical not mole fraction.
