在密闭容器中，NO（g）＋CO（g）
1/2N2（g）＋CO2（g）△H="-373.2" kJ/mol。达到平衡后，为了提高该反应的速率和NO的转换率，采取的措施正确的是（ ）
A．加催化剂同时升高温度
B．加催化剂同时增大压强
C．升高温度同时通入N2
D．降低温度同时增大压强
答案：B
此题两要求：①提高反应速率，②提高NO的转换率，即：使平衡右移；
加催化剂同时升高温度，均能提高反应速率，但△H＜0，正向为放热反应，而升温时平衡是向吸热反应的方向移动，即该反应的逆向移动，则NO的转换率减小，故A错误；
通入N2平衡逆向移动，则NO的转换率减小，故B错误；
降低温度，反应速率减小，故D错误；

Gaul Middle School is in Union, Maine, a blueberry-farming town where the summer fair finds kids competing in pig scrambles and pie-eating contests. Gaul, with about 170 seventh- and eighth-graders, has its own history of lower level academic achievement. One likely reason: Education beyond the basic requirements hasn't always been a top priority for families who've worked the same land for generations. Here, few adults have college degrees, and outsiders (teachers included) are often kept at a respectful distance. Since 2002, Gaul's students have been divided into four classes, each of them taught almost every subject by two teachers. The goal: To find common threads across disciplines to help students create a big picture that gives fresh meaning and context to their classwork -- and sparks motivation for learning. Working within state guidelines, each team makes its individual schedules and lesson plans, incorporating non-textbook literature, hands-on lab work and field trips. If students are covering the Civil War in social studies, they're reading The Red Badge of Courage or some other period literature in English class. In science, they study the viruses and bacteria that caused many deaths in the war. Team teaching isn't unusual. About 77 percent of middle schools now employ some form of it, says John Lounsbury, consulting editor for the National Middle School Association. But most schools use four- or five-person teams, which Gaul tried before considering two-person teams more effective. Gaul supports the team concept by "looping" classes (跟班) so that the same two teachers stick with the same teens through seventh and eighth grades. Combining teams and looping creates an extremely strong bond between teacher and student. It also, says teacher Beth Ahlholm, "allows us to build an excellent relationship with parents." Ahlholm and teammate Madelon Kelly are fully aware how many glazed looks they see in the classroom, but they know 72 percent of their eighth-graders met Maine's reading standard last year -- double the statewide average. Only 31 percent met the math standard, still better than the state average (21 percent). Their students also beat the state average in writing and science. And in2006, Gaul was one of 47 schools in the state to see testing gains of at least 20 percent in four of the previous five years, coinciding roughly with team teaching's arrival.
