DESCRIBE THE FAVOURABLE CONDITIONS FOR THE MANUFRACTURE OF :
1. NH3 BY HABER PROCESS.
2. H2SO4 BY CONTACT PROCESS.
The synthesis of NH3 is shown below.
According to Le Chateliar's principle the low temperature and high pressure is favourable. Increasing the pressure will shift the equilibrium in right as number of moles of reactant is more than product.Since the reaction is exothermic lowering of temperature is favourable.
The pressure and temperature use in manufacure of NH3 in haber process is shown in orange box in diagram above.
Synthesis of H2SO4 in contact process involves 2 steps.
1)synthesis of SO3
2)Reaction of SO3 with H2SO4 followed by reaction of product with water:
Since only first step involves equilibrium we will discuss the condition according to it.
According to Le Chateliar's principle the low temperature and high pressure is favourable. Increasing the pressure will shift the equilibrium in right as the number of moles of reactant is more than product.Since the reaction is exothermic lowering of temperature is favourable. But the condition used in industries are shown below:
