The running engine of an automobile produces carbon monoxide (CO), a toxic gas, at the rate of about 188 g CO per hour. A car is left idling in a poorly ventilated garage that is 6.0 m long,4.0 m wide, and 2.2 m high at 20°C. (a) Calculate the rate of CO production in mol/min. (b)How long would it take to build up a lethal concentration of CO of 1000 ppmv (parts per million by volume)? Round off to 4 sig. figures for all calculations made prior to final answer and the final answer should be in 3 sig. figures

Atomic diffusion in solids

In material science, diffusion can take place in solid, liquid, and gases. In solids, atomic diffusion can take place with the help of thermally activated and randomly vibrating atoms. The atomic diffusion in solids is complex and very slow in comparison to atomic diffusion in liquids and gases because the interatomic distance between the atoms is smaller in solids as compared to liquids and gases.
