A 22.4 litre flask contains 0.76 mm of ozone at `25^@C`. Calculate the rate of formatiuon of oxygen under this condition.

A 22.4 litre flask contains 0.76 mm of ozone at 25^@C . Calculate the concentration of oxygen atom needed so that the reaction O + O_3 to 2O_2 having rate constant equal to 1.5 xx 10^7 litre mol^(–1) sec^(–1) can proceed with a rate of 0.15 mol litre^(–1) sec^(–1) .

A flask P contains 0.5 mole of oxygen gas. Another flask Q contains 0.4 mole of ozone gas. Which of the two flasks contains greater number of oxygen atoms ?

A 2.5 L flask contains 0.25 mol each of sulphur dioxide and nitrogen gas at 27^(@)C . Calculate the partial pressure exerted by each gas and also the total pressure.

The molecular weights of oxygen and sulphur dioxide are 32 and 64 respectively. If 1 litre of oxygen are 32 and 64 respectively. If 1 litre of oxygen at 15^(@)C and 740 mm pressure contains N molecules, the number of molecules in 2 litre of sulphur dioxide under the same conditions of temperature and pressure will be

Calculate the volume of air, containing 21% of oxygen by volume required for the complet combustion of 10L of ethylene under similar conditions
