现就该副题第七题第1小题谈一下自己的看法: 原题在某高温下,NO_2分解(2NO_2(?)2NO+O_2)达到平衡时NO摩尔数占混和气体总摩尔数的40% (1)求平衡时NO的摩尔数。 (2)求平衡时NO_2和O_2摩尔数分别占混和气体总摩尔数的百分率。 (解答见本刊84年第1期) 我认为该题的第一问是无法求解的,另外,该题的整个计算过程都是有问题的。首先在题解中将NO_2的起始摩尔数设 Let’s talk about our own opinion about the first item of this subtitle question No.7: When the NO2 decomposition (2NO_2(?)2NO+O2) reaches equilibrium at the high temperature, the NO moles account for 40% of the total moles of gas mixture. (1) The number of moles of NO at equilibrium. (2) The percentage of moles of NO 2 and O 2 , respectively, in the total moles of gas mixture during equilibrium. (Answer, see the first issue of the 84th issue of this journal.) I think the first question of this question cannot be solved. In addition, the whole calculation process of this question is problematic. First set the initial mole number of NO 2 in the solution
