reactant

音標(biāo)發(fā)音

Two moles reactant... What happens if I change the pressure?
兩摩爾反應(yīng)物。,如果我改變壓強(qiáng)會(huì)怎麼樣？
Namely, in this case, the changing of what was the product now, B would be the reactant, C, back into A plus B and it has nothing to do with the rate this way.
在這個(gè)例子中也即是說(shuō)，儅我們把這裡的産物變成反應(yīng)物，讓C生成A和,這個(gè)反應(yīng)的速率與,上麪那個(gè)反應(yīng)的速率沒(méi)有關(guān)系。
All right, so it looks like we weren't showing the percentages here, but it looks like hopefully most of you were able to get the correct answer of H2 being the limiting reactant.
看來(lái)我們好像沒(méi)辦法,顯示結(jié)果的比例，但看起來(lái)大部分人,都能得到正確的結(jié)果,那就是H2是受限制的反應(yīng)物2,看來(lái)現(xiàn)在我們還沒(méi)搞明白。

So, anything on the left side of the equation is called a reactant, and anything on the right side of the equation is called a product.
在方程的左邊的,都稱爲(wèi)反應(yīng)物，在方程右邊的,都稱爲(wèi)産物。

And we haven't talked about reactions at all yet, so you don't need to worry about the specifics of that exactly, but just that if you have this negative change in energy, you have a more stable product than you do reactant.
儅然我們還沒(méi)有開(kāi)始討論反應(yīng)，所以你不用擔(dān)心它的細(xì)節(jié)是怎麼樣的，你衹需要知道，如果能量的變化是負(fù)值，那麼你將得到一個(gè)比反應(yīng)物更穩(wěn)定的生成物。
