How is ammonia manufactured by Haber's process ? Explain the reactions of ammonia with
`"AgCl"_((s))`

Explanation

On a large scale,.ammonia is manufactured by Haber.s process. `N_(2)(g) + 3H_(2)(g) rarr 2NH_(3)(g),triangle_(f)H^(@)= -46.1. kJ "mol"^(-1)` The optimum conditions for production of ammonia are a pressure of about `2000 xx 10^(5)` Pa and a temperature of 700K. iron oxide is the catalyst with small amounts of `K_(2)0` and `Al_(2)0_(3)`

. Compressed mixture of `N_(2)`and `H_(2)` in the volume ratio is heated .to 700K at a pressure of 200 atm and passed over finely divided Iron oxide mixed.with small amounts of `K_(2)0` and `Al_(2)0_(3)` . Ammonia formed Is liquified and unreacted mixture of `N_(2)` and `H_(2)` again pumped-irito catalytic chamber.
