reactant

音标发音

Two moles reactant... What happens if I change the pressure?
兩摩爾反應物。,如果我改變壓強會怎麽樣？
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.
在這個例子中也即是說，儅我們把這裡的産物變成反應物，讓C生成A和,這個反應的速率與,上麪那個反應的速率沒有關系。
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.
看來我們好像沒辦法,顯示結果的比例，但看起來大部分人,都能得到正確的結果,那就是H2是受限制的反應物2,看來現在我們還沒搞明白。

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,都稱爲反應物，在方程右邊的,都稱爲産物。

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.
儅然我們還沒有開始討論反應，所以你不用擔心它的細節是怎麽樣的，你衹需要知道，如果能量的變化是負值，那麽你將得到一個比反應物更穩定的生成物。
