Fertiliser Technology 5-10-5 fertilisers mean that they contain None of these 5, 10, 5% respectively of N₂, P₂O₅ and K₂O 5 to 10% filler & carrier of soil conditioners Only 5 to 10% active fertiliser constituents None of these 5, 10, 5% respectively of N₂, P₂O₅ and K₂O 5 to 10% filler & carrier of soil conditioners Only 5 to 10% active fertiliser constituents ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology In ammonia synthesis (N₂ + 3H₂ = 2NH₃), there is a decrease in total volume, hence to get high equilibrium conversion, the reaction should be carried out at Atmospheric pressure; as the pressure has no effect on conversion Very high temperature High pressure Low pressure Atmospheric pressure; as the pressure has no effect on conversion Very high temperature High pressure Low pressure ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Which of the following fertilisers is used as a cattle feed? Calcium ammonium nitrate Urea Ammonium sulphate Superphosphate Calcium ammonium nitrate Urea Ammonium sulphate Superphosphate 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
