This allowed the forward reaction to keep going faster than the reverse reaction.

这使得正向反应比逆向反应继续进行得更快。

So the forward reaction decreases the volume while the reverse reaction increases it.

因此正向反应减少体积而逆向反应增加体积。

When reactants react to form products, what we usually mean when we talk about chemical reactions, it's technically called the forward reaction.

当反应物反应生成产物时， 也就是我们通常所说的化学反应，在技术上称为正向反应。

As nitrogen and hydrogen react to form ammonia, the concentration of those gases drops, making them less likely to collide and keep reacting, so the rate of the forward reaction slows down.

当氮气和氢气反应形成氨时，这些气体的浓度下降， 使它们不太可能发生碰撞并继续反应， 因此正向反应的速度会减慢。
