Fertiliser Technology Iron is not used alone as a catalyst in ammonia synthesis, because Its activity declines rapidly, if heated to above 520°C None of these It decomposes ammonia It gets oxidised above 500°C Its activity declines rapidly, if heated to above 520°C None of these It decomposes ammonia It gets oxidised above 500°C 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 High pressure Very high temperature Low pressure Atmospheric pressure; as the pressure has no effect on conversion High pressure Very high temperature Low pressure ANSWER DOWNLOAD EXAMIANS APP
