Ammonia gas is produced by the reaction between nitrogen gas and hydrogen gas at a temperature of 550°C and at 200 atmosphoric pressure in the presence of iron as a catalyst. Represent this reaction by a balanced chemical equation.

Write the balanced chemical equation for the reaction between sulphur di oxide and chlo-rine in presence of charcoal as catalyst.

At what temperature the velocity of hydrogen gas molecule becomes twice at normal temperature and pressure.

For a certain mas of the gas at constant temperature draw a graph between the volume against the corresponding pressure i.e. V vs P.

2.0mol of N_2 gas is kept in a vessel of volume 0.020m^3 and the temperature was maintained at 60^@C . Calculate the pressure of the gas.(Assume that N_2 gas is ideal)

How pure N_2 gas is prepared in laboratory? Write the necessary equation for the reaction.

A cylinder with a movable piston contains 3 moles of hydrogen at standard temperature and pressure. The walls of the cylinder are made of a heat insulator, and the piston is insulated by having a pile of sand on it. By what factor does the pressure of the gas increase if the gas is compressed to half its original volume?

One mole of an ideal gas at standard temperature and pressure occupies 22.4 L (molar volume). What 'is the ratio of molar volume to the atomic volume of a mole of hydrogen?
