1. Consider a mixture of ethylene oxide (abbreviated EO) gas, C2H2O, in air. You want to remove the EO by passing the air over porous media such as activated carbon, with the EO getting "trapped" inside the pores of the media. The average pore diameter of the porous material is 12.3nm and the void fraction () is 0.4. The system operates at 2.6atm total pressure and a temperature of 35C. Use an appropriate method to calculate the binary diffusion coefficient of EO in air, DN, and then use that value to calculate the effective diffusion coefficient, DSe, of EO in air inside the porous material. Though EO is somewhat polar, you can neglect that and use one of the expressions that was not specifically developed for polar gases
