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 Space velocity of gas is very low resulting in decreased conversion None of these Very high pressure is required resulting in costly pressure vessel Rate of reaction is very low Space velocity of gas is very low resulting in decreased conversion None of these Very high pressure is required resulting in costly pressure vessel ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Iron is not used alone as a catalyst in ammonia synthesis, because It decomposes ammonia Its activity declines rapidly, if heated to above 520°C None of these It gets oxidised above 500°C It decomposes ammonia Its activity declines rapidly, if heated to above 520°C None of these It gets oxidised above 500°C ANSWER DOWNLOAD EXAMIANS APP
