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。

Well sometimes the reverse reaction isn't as thermodynamic spontaneous for one reason or another.

好吧，有时由于某种原因，逆反应不是热力学自发的。

And since exothermic reactions produce heat, that heat tends to favor the reverse endothermic reactions.

由于放热反应会产生热量， 因此热量往往有利于反向吸热反应。

And surprise, the rate of the reverse reaction speeds up.

令人惊讶的是， 逆反应的速度加快了。

So if " Delta G" is positive, the reaction is non-spontaneous, but the reverse reaction is spontaneous.

所以如果“Delta G” 为正，则反应是非自发的， 而逆反应是自发的。

And when the forward and reverse reactions occur at the same rate, that's called chemical equilibrium.

当正向和反向反应以相同的速率发生时， 这就是所谓的化学平衡。

Often though it's just that the reverse reaction has such a high activation energy that the collisions are almost always ineffective.

通常，只是反向反应具有如此高的活化能，以至于碰撞几乎总是无效的。

The scientists described it as a sort of reverse chemical combustion reaction, since they started with a waste product and ended up with fuel.

科学家将其描述为一种逆向化学燃烧反应，因为他们从废物开始，最终得到燃料。
