Composition of the equilibrium mixture `(Cl_(2) hArr 2Cl)`. Which is attained at `1200^(@)C`, is determined by measuring rate of effusion through a pin-hole. It is observed that at 1.80 mmHg pressure, the mixture effuses 1.16 times as fast as Kryptom effuses under the same conditions. calculate the fraction of chlorine molecules dissociated into atoms. (Relative atomic mass of Kr=84).

50 ml of gas A effuse through a pin -hole in 146 second . The same volume of CO_2 under identical condition effuse in 115 seconds . Calculate the molecular mass of A .

1 L of a mixture of CO and CO_(2) , when passed through red hot tube containing charcoal, the volume becomes 1.6 L. all volumes are measured under the same conditions of temperature and pressure. Find the composition of the mixture.

75ml of gas A effuses through a pin hole in 73 seconds. The same volume of SO_2 under identical conditions effuses in 75 seconds. Calculate the molecular mass of A.

In a mixture of O_(2) and an unknown gas, the percentage of the unknown gas is 20% by mass. At a given temperature and pressure, time required to effuse V mL of the gas mixture through an aperrture is 234.1 s. under the same conditions, time required to effuse the same volume of pure O_(2) gas is 223.1 s. what is the molar mass of unknown gas?

Under idential conditoins of temperature and pressure, it takes time t_(1) for the effusion of VmL of N_(2) gas through a porous wall and the time t_(2) for the effusion of the same volume of CO_(2) gas through the same porous wall. Which one is greater t_(1) or t_(2) ?

Density of the vapour of a substance at 1 atm and 500K is 0.36 Kg*m^(-3) . The vapour effuses through a hole at a rate of 1.13 times faster than O_(2) under same conditon. (i) Determine (a) molar mass (b) molar volume (c) compression factor (Z) of the vapour nand (d) which forces among the gas molecules are dominating-attractive or repulsive? (ii) if vapour behaves ideally at 1000K, find average translational kinetic energy of a molecule.

Under similar conditions of temperature and pressures, if the time taken for effusion of the same volume of H_(2),N_(2) and CO_(2) gas through the same porour wall are t_(1),t_(2) and t_(3) respectively, then arrange t_(1),t_(2) and t_(3) in their increasing order.
