题型:填空题

题目:

现有反应:CO(g)+H2O(g)⇌CO2(g)+H2(g)(放热)在85手k时,k=大.

(大)若升温至95手℃,达平衡时k______大(填“大于”“小于”“等于”)

(2)85手℃时,在固定容积的密闭容器中,放入混合物,起始浓渡C(co)=手.大mol/L,C(H2O)=手.3mol/L,C(CO2)=手.大mol/L,C(H2)=手.5mol/L,则反应开始时,H2O消耗速率比生成速率______(填“大”、“小”或“不能确定”)

(3)保持温度不变,容器的体积不变,当往容器中充入适量的H2S气体,则重新达到平衡时,CO的反应速率比充入H2S气体之前______(填“增大”、“减小”或“不能确定”)理由是______.

DOM is a platform- and language- () API that allows programs and scripts to dynamically access and update the content, structure and style of WWW documents (currently, definitions for HTML and XML documents are part of the specification). The document can be further processed and the results of that processing can be incorporated back into the presented () . DOM is a () -based API to documents, which requires the whole document to be represented in () while processing it. A simpler alternative to DOM is the event-based SAX, which can be used to process very large () documents that do not fit into the memory available for processing.

The document can be further processed and the results of that processing can be incorporated back into the presented ().

A.text

B.image

C.page

D.graphic
