(a) Draw the structure of following (i) XeF_6 (i) XeOF_4 Describethe harber process for manufacture of ammonia |
Answer» Solution :(a) Structure of (b) Haber.s process for the manufacture of` NH_3`(By synthesis) `N_2(g) + 3H_2(g) iff 2NH_3 (g) "" Delta H = -92.4 kJ` According to Lechatelier.s principle, the favourable CONDITIONS for the manufacture of `NH_3`are low temperature (700 K), HIGH pressure (400-600 atm) and presence of a catalyst `Fe_2O_3//Mo` `N_2` and `H_2` are mixed in the ratio 1 : 3 by volume and compressed to a pressure of 400-600 atm and then passed through catalyst chamber at 700 K. Here `NH_3`is PRODUCED which is condensed to GET liquid `NH_3` . The unreacted gases are mixed with more of `N_2`and `H_2` , compressed and passed through catalyst chamber. |
