4NO2g4NOg的精选

问题详情：一定条件下用**可以消除氮氧化物(NOx)的污染。已知：  ①CH4(g)＋4NO2(g)==4NO(g)＋CO2(g)＋2H2O(g)；ΔH＝－574kJ·mol－1  ②CH4(g)＋4NO(g)==2N2(g)＋CO2(g)＋2H2O(g)；ΔH＝－1160kJ·mol－1下列说法不正确的是       A．由反...

问题详情：用CH4催化还原NOx可以消除氮氧化物的污染。已知CH4(g)＋4NO2(g)===4NO(g)＋CO2(g)＋2H2O(g)ΔH＝－574kJ·mol－1，CH4(g)＋4NO(g)===2N2(g)＋CO2(g)＋2H2O(g)ΔH＝－1160kJ·mol－1。若在标准状况下4.48LCH4恰好能将一定量NO2还原成N2...

问题详情：用CH4催化还原NOx，可以消除氮氧化物的污染。例如：①CH4(g)＋4NO2(g)===4NO(g)＋CO2(g)＋2H2O(g)ΔH＝－574kJ·mol－1②CH4(g)＋4NO(g)===2N2(g)＋CO2(g)＋2H2O(g)ΔH＝－1160kJ·mol－1下列说法不正确的是()A．若用标准状况下4.48LCH4还...
