Question

potassium permanganate KMnO4 of different concentrations n and n n n molecules pe unit volume with An n n n When they are connected by a tube of small length and cross sectional area S KMnO4 starts to diffuse from the left to the right vessel through the tube Consider the collection of molecules to behave as dilute ideal gases and the difference in thei partial pressure in the two vessels causing the diffusion The speed v of the molecules is limited by the viscous force Bv on each molecule where is a constant Neglecting all terms of the orde An which of the following is are correct ks is the Boltzmann constant 12 A the force causing the molecules to move across the tube is AnkBTS B force balance implies ni vl AnkBT ALLEN CAREER INSTITUTE DANGEROUS AnkaT C total number of molecules going across the tube per sec is 47 S D rate of molecules getting transferred through the tube does not change with time Ans A B C Sol n n n An n RT NA P n P n v Ank T JEE Advanced 2020 Paper 1 Held on Sunday 27 September 2020 F n n kBTS AnkBTS A V Ank TS B ts 122 B n RT NA Force balance Pressure Area Total number of molecules Bv Ank TS n S v Total number of molecules ser n vdt S JEE Advanced 2020 Paper 1
