so here is the question ...

One side of glass cylinder is initially filled with H2 at pressure P and other side with N2 at pressure 2P . This glass cylinder is closed at both ends and a glass filter in middle of cylinder divides into two compartments of equal volume . Describe what happens starting at time t = 0 at constant temperature and assuming that pores of filter have a diameter much smaller than mean free path of gases

i know H2 and N2 will not react ....so maybe this question is about rate of effusion i.e. grahams law = r1/r2 = P1/P2 X square root of (M2/M1)

my only doubt is what does the line - ' pores of filter have a diameter much smaller than mean free path of gases ' mean ?

i know mean free path is distance between two successive collision

please help ??

calculate internal energy when 1 mole of H2O goes from 25 degree C at 1 atm pressure goes to 30 degree C at 1 atm pressure . . Densities of water are 0.997 g/cm^3 at 0 degree C and 0.995 g/cm^3 at 100 degree C

Two guns were fired from the same place at an interval of 10 minustes and 30 seconds, but a person in a train approaching the place hears second shot 10 minutes after the first. The speed of train (in km/hr), supposing that sound travels at 330m/s is ??

i just want to know why distance covered by sound in 30 seconds is equal to distance covered by train in 10 minutes ??

explain why carbene (A) does not react with cyclohexene in a manner of ordinary carbenes but does react with dimethyl fumarate (B) and maleate (c) to yield spiropentanes (D)
