求翻译这句话? at high temperature finely divided titanium reacts with n2 to give a stable nitride. the rate-determining step in ammonia synthesis with iron catalysts is cleavage of the n≡n bond. why is titanium inactive and iron active as a catalyst for ammonia synthesis? 高温条件下,钛粉与氮气反应生成稳定的氮化物。在以铁作为催化剂的合成氨反应中,其反应速率决定步骤是n≡n键的裂解。铁可以作为合成氨反应的催化剂而钛却不可以的原因为何?查看更多
