प्रश्न

The reaction 4N2O + CH4 → CO2 + 2H2O + 4N2 takes place in the gaseous state. If the volumes of all the gases are measured at the same temperature, and pressure, calculate the volume of dinitrogen oxide (N2O), required to give 150cm3 of steam.

योग

उत्तर

According to Gay-Lussac's law : In the equation
4N2O + CH4 → CO2 + 2H2O + 4N2
Vol. of H2O produced is = 2 vol. = 150cm3
Vol. of N2O required is = 4 vol. = 150 x 4 / 2 = 300 cm3
300cm3 of dinitrogen oxide (N2O) is required to give 150 cm3 of steam.

The volumes of gases A, B, C and D are in the ratio, 1 : 2 : 2 : 4 under the same conditions of temperature and pressure.

  1. Which sample of gas contains the maximum number of molecules?
  2. If the temperature and pressure of gas A are kept constant, then what will happen to the volume of A when the number of molecules is doubled?
  3. If this ratio of gas volume refers to the reactants and products of a reaction, which gas law is being observed?
  4. If the volume of A is actually 5.6 dm3 at STP, calculate the number of molecules in the actual Volume of D at STP (Avogadro's number is 6 × 1023).
  5. Using your answer from (iv), state the mass of D if the gas is dinitrogen oxide (N2O).
