Assume that an ideal gas of NH3 is placed in an isolated container of 1,600 cm3 at 298 K. When the container is heated to 500 K, NH3 is partially decomposed to N2 and H2. The pressure is found to be 4.50 MPa. Find the number of moles of NH3, N2 and H2.

Answer #1

Either we have to specify the initial pressure or we have to consider that initial 1 mole of NH3.

There after pressure will depends on the mole and temperature since volume is constant throughout the pressure.

#5.133 A mixture of NH3(g) and N2H4(g) is placed in a sealed container at 320 K . The total pressure is 0.53 bar . The container is heated to 1200 K at which time both substances decompose completely according to the equations 2NH3(g)→N2(g)+3H2(g) ; N2H4(g)→N2(g)+2H2(g) . After decomposition is complete the total pressure at 1200 K is found to be 4.5 bar. Find the percent (by volume) of N2H4(g) in the original mixture. (Assume two significant figures for the temperature.)

. A container has n = 3 moles of a monoatomic ideal gas at a temperature of 330 K and an initial pressure of three times the atmospheric pressure. The gas is taken through the following thermodynamic cycle: 1.- The gas is expanded isobarically (constant pressure) to Vf = 2.5∙Vi. 2.- The pressure of the gas is decreased isochorically (constant volume) to half of the initial value. 3.- The gas is compressed isobarically back to its initial volume. 4.- The...
