One gram mole `NO_2 "at" 47^@ C` and 2 atm pressure in kept in a vessel. Assuming the molecules to be moving with (rms) velocity. Find the number of collisions per which the molecules make with one square metre area of the vessel wall.

1 g mole of oxygen at 27^@ C and (1) atmosphere pressure is enclosed in a vessel. (a) Assuming the molecules to be moving with (v_(r m s) , find the number of collisions per second which the molecules make with one square metre area of the vessel wall. (b) The vessel is next thermally insulated and moves with a constant speed (v_(0) . It is then suddenly stoppes. The process results in a rise of temperature of the temperature of the gas by 1^@ C . Calculate the speed v_0.[k = 1.38 xx 10^-23 J//K and N_(A) = 6.02 xx 10^23 //mol] .

One gram mole of oxygen at 27^@C and one atmospheric pressure is enclosed in a vessel. Assuming the molecules to be moving with v_(rms) , find the number of collisions per second which the molecules make against one square metre of the vessel wall.

A cubical vessel of side 1 m contains one mole of nitrogen at a temperature of 300 K. If the molecuels are assuming to move with the rms velocity find the number of collisions per second which the molecules may make with the wall of the vessel

1 mol O_2 at temperature 27^@C at STP (1.01 times 10^5 N/m^2) is kept in a vessel.Find the number of collisions the molecules experience(in SI) per second per unit area with the wall of the vessel. [Given Boltzmann constant k= 1.38 times 10^-23 J//K ]
