The mole faction of co2 in air is 0.00033 at present and rising. co2 is known to have its triple point (first vle point) at -56.4°c and 5.11 atm and its critical point (last vle point) at t. = 304.2 k and p 73.83 bar = ahyap > 1 always holds. briefly explain if co2 have a normal boiling (a) considering the fact that az"ap temperature? (b) use the corresponding-state "short-cut" method and a-0.224 (table b.1) to obtain a hypothetical normal boiling temperature for co2. (c) use the following antoine equation provided by national institute of standards and technology (nist) to estimate the hypothetical normal boiling point of co2. how do (b) and (c) compare to reported value of -78.5 °c? 1301.679 log10 p(bar 6.81228 - t(°c) 269.656 (d) one way to remove/reduce co2 from/in the air is to compress air to liquefy co2. is it thermodynamically possible at 25°c?
