Thank you for your cooperation! The topic for this activity is taken from the book \"Fertilizer Production Operators\". True or False: 1. The main function of an ammonia synthesis catalyst is to weaken the nitrogen triple bond and reduce the activation energy of the hydrogenation reaction. ( ) 1. √, 2. ×, 3. ×, 4. ×, 5. ×. 2. The iron ratio of ammonia synthesis catalysts refers to the ratio of reduced iron to oxidized iron in the catalyst. （ ） 3. In different ammonia synthesis processes, the pressure in the synthesis loop mainly depends on the level of equipment manufacturing. （ ） 4. Under the same fresh gas load, the higher the ammonia content at the outlet of the synthesis tower, the higher the ammonia production. （ ） 5. The optimal temperature range for the ammonia synthesis reaction is independent of catalyst activity. ( )
