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.
very high pressure is required resulting in costly pressure vessel.
space velocity of gas is very low resulting in decreased conversion.
none of these
Correct Answer:
rate of reaction is very low.
