1. Write the general equation which relates the different variables of a gas used to describe the state of any ideal gas. 2. A flask at 295 K contains a gaseous mixture of N2 and O2 at a total pressure of 1.8 atm. If 0.2 moels of N2 and 0.6 moles of O2 are present, find the partial pressures of N2 and O2 . 3. What is meant by Boyle temperature or Boyle point? |

Answer» 1. PV = nRT 2. XN2 = \(\frac{nN_2}{nN_2+no_2}\) = \(\frac{0.2}{0.8}\) = 0.25 Xo2 = 1 - 0.25 = 0.75 pN2 = XN2 x PTotal = 0.25 x1.8 atm = 0.45 atm po2 = Xo2 x PTotal = 0.75 x1.8 atm = 1.35 atm 3. It is the temperature at which a real gas obeys ideal gas law over an appreciable range of pressure. |
