This post was last edited by TH373637 on 2011-10-20 at 21:21. True or False questions: 1. Choosing an appropriate catalyst for ammonia synthesis can effectively reduce the reaction heat. 2. When maintaining large pressure vessels, maintenance workers can enter after performing multiple nitrogen purging operations. 3. When using gas from cylinders, it is necessary to use up as much of the gas as possible to avoid waste. The purpose of the “One Question per Day on Basic Knowledge of Ammonia Synthesis” activity is to review the knowledge we have already learned, to improve and strengthen everyone’s fundamental theoretical knowledge through answering questions, to help those who have forgotten to recall that information, to encourage discussion on controversial points, and to promote mutual progress. The top 50 answerers will definitely receive a reward. Those who simply state the reasons for their choice will be given additional points as appropriate!
