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 higher than that of the plant sap Soil becomes too acidic Osmotic pressure of the soil water becomes less than that of the plant sap Soil becomes too alkaline Osmotic pressure of the soil water becomes higher than that of the plant sap Soil becomes too acidic Osmotic pressure of the soil water becomes less than that of the plant sap Soil becomes too alkaline ANSWER DOWNLOAD EXAMIANS APP

Fertiliser Technology Though kinetics of ammonia synthesis dictates the use of low temperature for high equilibrium conversion, yet it is kept moderately high (550°C), because at low temperature Space velocity of gas is very low resulting in decreased conversion Rate of reaction is very low Very high pressure is required resulting in costly pressure vessel None of these Space velocity of gas is very low resulting in decreased conversion Rate of reaction is very low Very high pressure is required resulting in costly pressure vessel None of these ANSWER DOWNLOAD EXAMIANS APP
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 Higher pumping cost High cost of the high pressure vessel used for the reactor Comparatively higher pressure drop Chances of entrainment and disturbance of catalyst bed Higher pumping cost High cost of the high pressure vessel used for the reactor Comparatively higher pressure drop ANSWER DOWNLOAD EXAMIANS APP
