请帮忙翻译下面这段对我来说比较棘手的英文!? at a given temperature ,the rate of a reaction varies directly as the product of the concentrations of the reactants in the slowest step.for the reaction h2(g)+i2(g)→2hi(g),the rate expression was rate=k[h2][i2].for the general reaction a+b→c,the rate expression would be rate=k[a][b].hydrogen iodide decomposes into hydrogen and iodine.the equation is 2hi(g)→h2(g)+i2(g).this reaction is hi+hi→h2+i2.the rate expression(if it is a one-step reaction) is rate =k[hi][hi],or rate =k[hi]2. 最完整的翻译应该是:在某一给定温度下,反应速率与最慢的那个反应步骤中的反应物浓度的乘积成正比。对于反应h2(g)+i2(g)→2hi(g),反应速率表达式为:r=k[h2][i2]. 对于一般反应 a+b→c,反应速率表达式为:r=k[a][b]。对于碘化氢分解为氢气和碘,反应方程式为2hi(g)→h2(g)+i2(g).这个反应是一个碘化氢分子和另一个碘化氢分子结合生成一个氢气分子和一个碘分子。.反应速率表达式(如果是一步反应)为r=k[hi][hi],或者r=k[hi]2. 我觉得在这个句子中也要有一定的意译成分,并且要从专业的反应动力学机理去考察,不然句子就会显得很死板。比如:hydrogen iodide decomposes into hydrogen and iodine.the equation is 2hi(g)→h2(g)+i2(g).this reaction is hi+hi→h2+i2.查看更多
