Fertiliser Technology Multistage operation (as in the case of catalytic oxidation of SO₂) is not carried out for NH₃ synthesis, because of Chances of entrainment and disturbance of catalyst bed High cost of the high pressure vessel used for the reactor Comparatively higher pressure drop Higher pumping cost Chances of entrainment and disturbance of catalyst bed High cost of the high pressure vessel used for the reactor Comparatively higher pressure drop Higher pumping cost ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Ammonium nitrate (is mixed with limestone) is not used as fertiliser as such, because Its nitrogen content is very less It is highly acidic in nature It is a liquid at room temperature It is hygroscopic and explosive in nature Its nitrogen content is very less It is highly acidic in nature It is a liquid at room temperature It is hygroscopic and explosive in nature ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology A phosphatic fertiliser contains 16% P₂O₅. It could be Superphosphate Triple superphosphate Dicalcium phosphate None of these Superphosphate Triple superphosphate Dicalcium phosphate None of these ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Fertiliser plants get their N₂ requirements By dissociating oxides of nitrogen From coal gas (coke oven gas) From producer gas By fractionation of liquified air By dissociating oxides of nitrogen From coal gas (coke oven gas) From producer gas By fractionation of liquified air ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Excessive use of chemical fertilisers causes shrivelling of the roots and wilting of the plant, because the Osmotic pressure of the soil water becomes less than that of the plant sap Soil becomes too acidic Osmotic pressure of the soil water becomes higher than that of the plant sap Soil becomes too alkaline Osmotic pressure of the soil water becomes less than that of the plant sap Soil becomes too acidic Osmotic pressure of the soil water becomes higher than that of the plant sap Soil becomes too alkaline ANSWER DOWNLOAD EXAMIANS APP
