较难的单词（B2+）
Last week, I told you about equilibrium, which is, BRUCE, if you ever needed proof that the universe is trying to mess with us. Because, even though we think and talk about chemical reactions as being a straightforward process, oftentimes, they're also going backwards.
At the same time that reactants are combining to form products like nitrogen and hydrogen to make ammonia, or hydrogen and fluorine to make hydrogen fluoride, the products are also breaking back apart into the reactants. So there's a sweet spot.
One particular ratio of reactants to products, where the products form at the same rate that they break down. When a reaction hits that spot, it's said to be in its equilibrium state. Bit of a kick in the head.
