Fertiliser Technology Lower temperature and large excess of ammonia in urea melt Does not effect biuret formation Increases biuret formation Is undersirable Decreases biuret formation Does not effect biuret formation Increases biuret formation Is undersirable Decreases biuret formation ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Though liquid ammonia itself is a fertiliser (with 82% nitrogen content) yet it is commonly not used as such in a tropical country like India, because it Vaporises at normal temperature Is in short supply Is toxic and highly corrosive Has a pungent smell Vaporises at normal temperature Is in short supply Is toxic and highly corrosive Has a pungent smell ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Yield of urea can be increased with excess ammonia and higher pressure & temperature, but because of __________ this is normally not done. All of these High corrosion rate Increased biuret formation Increased cost of equipment All of these High corrosion rate Increased biuret formation Increased cost of equipment 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 Rate of reaction is very low None of these Space velocity of gas is very low resulting in decreased conversion Very high pressure is required resulting in costly pressure vessel Rate of reaction is very low None of these Space velocity of gas is very low resulting in decreased conversion Very high pressure is required resulting in costly pressure vessel ANSWER DOWNLOAD EXAMIANS APP
