Hydrogen cyanide (hcn) can also be produced by gas-phase nitrogenation of acetylene (c2h2) according to the reaction 3) n2 (g) + c2h2 (g) ←+ 2hcn (g) the feed to the reactor consists of gaseous n2 and c2h2 in their stoichiometric proportions and the reaction temperature is controlled at 573 k. estimate the maximum mole fraction of hcn in the product stream for a reactor pressure of 200 bar. at this pressure, the assumption of ideal gas behavior is not valid. instead, you can assume the gas mixture is an ideal solution. data: critical temperature (to) of n2 126.2 k critical pressure (pofna-33.9 bar acentric factor (a) of n2 -0.04 critical pressure (p) of cah2-61.4 bar acentric factor (a) of ch2-0.184 critical temperature (to) of hcn 456.7 k critical pressure (p) of hcn-49.6 bar acentric factor (a) of hcn-0.4 standard gibbs free energy of reaction at 573 k-( 0".1 klmole critical temperature (te) of cah2-308.3
