第一节短文改错(共10小题;每小题1分,满分10分)Duanwu Festival, which is also known for Dragon Boat Festival, is a traditional holidayoriginate in China. It is associated with a number of East Asian and Southeast Asian tradition(originated/originating③ traditionsIn Chinese, it's known as Duanwu jie. The festival fall on the fifth day of fifth month accordin④falsto the Chinese lunar calendar. This year the holiday is on June 25th. The celebrations are heldeach year in the memory of the death of Qu Yuan, a devoted poet which lived during the Warring⑥ who/thatStates Period about 2,000 years ago.

16.(14分)【答案】1.-22686(1分)Ⅱ.(1)①>、<、>、>(4分)②CD(2分)(2)①1:0.5(2分)②该可逆反应的正反应是放热反应,升温,平衡向左移动NO2的平衡转化率降低;当温度升高一定程度时温度对反应影响起主要作用,投料比因素可以忽略(等合理答案)(3分)③0.44(或9)(2分)【解析】1.根据盖斯定律知,量=1 1×2--196,mx-1303,mⅡ.(1)①从反应条件看,以甲容器为参照,该反应是放热反应,乙容器的温度高于甲,相当于甲到乙时,平衡228.6k向左移动,NO的平衡转化率减小;该反应是等气体分子数反应,气体分子数不变,但是温度升高,气体压强增大NO体积分数减小;平衡常数减小,②在恒温恒容条件下,气体密度始终不变,A项错误;气体总质量不变,气体总物质的量不变,故混合气体摩尔质量始终不变,B项错误;SO3的浓度不变,表明正、逆反应速率相等,C项正确;NO和NO的生成速率相等,说明NO的生成速率等于消耗速率,D项正确。故选C、D(2)①相同温度下,n(SO2):n(NO3)(投料比)越大,NO2的转化率越大,曲线a代表投料为1:0.5;②分两段解释:前一段(温度较低),从温度对平衡影响角度解释;后一段,当温度较高时,投料比影响较小,温度影响较大,故转化率趋于相等③A点代表的投料比为1:1,设A点总压强为pNO, (g) SO,(g)mSO, (g) NO(g)起始物质的量/mol1转化物质的量/mol0.40.40.40.4平衡物质的量/mol0.60.40.各组分的物质的量分数分别是:(SO3)=g(NO3)=30%,g(SO3)=(NO)=20%,分压分别是:p(SO2)=pN)=平pSO)-NO)=023,K=2503=32x032==04
