Question

Hey guys plzz gimme the suitable conditions for highr yield of ammonia....

Answer 1

Hey mate >>>>>>>>>>>>>.



here is u answer!!!!!!!!!!!!

but mark me as brainlist @@@@@@@@@@@@@@@@




the conditions required to maximise the yield of ammonia. ... 2 High pressure on the reaction at equilibrium favours the shift of the equilibrium to the right because the forward reaction proceeds with a decrease in number of moles.Hence a pressure of about 200 atm will be optimal for the higher yield of ammonia.

Answer 2

hey this is your answer

Ammonia is prepared using the Haber’s process.

Amonia

The conditions required to maximize the yield of ammonia are as follows:

1 In accordance to Le Chatelier’s principle ,low temperature will shift the equilibrium to the right because the reaction is exothermic.This gives greater yield of ammonia.Therefore a temperature of about 450°C will be optimal for the preparation of ammonia.

2  High pressure on the reaction at equilibrium favours the shift of the equilibrium to the right because the forward reaction proceeds with a decrease in number of moles.Hence a pressure of about 200 atm will be optimal  for the higher yield of ammonia.

3 A catalyst should be used to increase the rate of reaction & to quickly attain equilibrium.For eg as iron oxide mixed with small amounts of K2O and Al2O3  can be used as catalyst.

4 N2 & H2 gases should be pure in nature to increase the yield of ammonia.

hope it help u mark me
