一、提出问题题目在1.0L密闭容器中放入0.10mol A(g),在一定温度下进行如下反应:A(g)幑幐B(g)+C(g),ΔH=+85.1kJ·mol-1。反应时间(t)与容器内气体总压强(p)的数据见表1:由总压强p和起始压强p0,列式并计算反应的平衡常数K。2.研究过程(1)测试调查在2014年元月中旬进行,对象是本校2014届高三年级部分班级48位学生,在规定时间内进行了本专题相关练习,共取得48份有效资料,占总人数的100%。经统计,调查卷有关此题答题情况的数据整理如表2:
First, the question asked Put a 1.0L airtight container 0.10mol A (g), at a certain temperature reaction as follows: A (g) 幑 幐 B (g) + C (g), ΔH = +85.1kJ · mol-1. The reaction time (t) and the total gas pressure in the vessel (p) are shown in Table 1: The equilibrium constant K is calculated from the total pressure p and the starting pressure p0, and the equation. 2. Research Process (1) The test survey was conducted in mid-January 2014. The survey was conducted for 48 students in some classes of the 2014 senior year of 2014 in our school. During the specified time period, relevant exercises on this topic were conducted. A total of 48 valid data were collected, 100% of the population. According to the statistics, the data of the survey questionnaire about the answer to the question is as shown in Table 2:
