Text Solution

Verified by Experts


`N_2(g) + 3H_2(g) The most favorable condition according to Le-Chatelier.s principle.
(i) The temperature is about 770 K (low temp)
(ii) The pressure is about `200 xx 10^(5) Pa` (high pressure)
(iii) Iron oxide catalyst with small amounts `K_2O //Al_2O_3` prometer.
OR
`N_2(g) + 3H_2(g) underset("Iron oxide &" K_2O //Al_2O_3)overset(770K, 200 "bar")(rarr) 2NH_3(g), Delta H_(f)^(0) = -46kJ//mol` .
