What is the reaction in the harbour process |
N2(g)+ 3H2(g) equilibrium 2NH3 (g) + heat |
|
|
What pressure is the harbour process at and why |
200 atmospheres How is possible to give best yield without making plans to expensive to build |
|
|
What temperature is the harbour process at and why |
450°c forward reaction is exothermic so increasing temperature would move equilibrium position the wrong way lower temperatures mean lower rate of reaction 450°is a compromise between maximum yield and speed of reaction |
|
|
What are the three essential elements in fertilisers |
Nitrogen phosphorus and potassium |
|
|
Method to prepare the fertiliser ammonium sulphate |
Put Ammonium solution and indicator into flask set up burette over it slowly add dilute sulphuric acid until the indicator changes colour to show its neutralise do it again and put in the exact same amount of dilute sulphuric acid |
