4NO2g4NOg的精選

問題詳情：用CH4催化還原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。若在標準狀況下4.48LCH4恰好能將一定量NO2還原成N2...

問題詳情：用CH4催化還原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下列說法不正確的是()A．若用標準狀況下4.48LCH4還...

問題詳情：一定條件下用**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下列說法不正確的是       A．由反...
