一、特征法对题干和选择支的特点进行分析,发现隐含信息,得出正确判断的方法。例1在一个不导热的密闭反应器中,只发生两个反应:A(g)+B(g)幑幐2C(g),ΔH<0X(g)+3Y(g)幑幐2Z(g),ΔH>0进行相关操作且达到平衡后(忽略体积改变所做的功),下列叙述错误的是()A.等压时,通入惰性气体,C的物质的量不变 First, the characteristic method to analyze the characteristics of the subject and the choice of support, found that implicit information, come to the correct way to judge. Example 1 In a heat-conducting hermetic reactor, only two reactions occur: A (g) + B (g) 幑 幐 2C (g), ΔH 0 0X (g) + 3Y (g) 幑 幐 2Z ), ΔH> 0 after the relevant operation and reach equilibrium (ignoring the work done by the volume change), the following error is () A. Isobaric, the introduction of inert gas, C constant amount of substance
