Consider the following two cases for a binary mixture of ideal gases A and B under steady state conditions. In case 1, the diffusion of A occurs through non-diffusing B. In case 2, equimolar counter diffusion of A and B occurs. In both the cases the total pressure is 100 kPa and partial pressure of A at two points separated by a distance of 10 mm are 10 kPa and 5 kPa. What is the ratio of molar flux of A in case 1 to that in case 2
