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

Very high pressure is required resulting in costly pressure vessel
None of these
Rate of reaction is very low
Space velocity of gas is very low resulting in decreased conversion
