拖动速率滑块,看 A ⇌ B 如何滑向平衡 —— 这正是「知识点讲思维」的样子:不是背"平衡态",是看见它怎么到达。 Drag the rate sliders and watch A ⇌ B slide into equilibrium — this is how our knowledge points teach thinking: not memorizing "equilibrium", but seeing it emerge.
每个粒子随机转化;正向/逆向速率不同,计数收敛到稳定比。 Each particle converts randomly; forward/reverse rates differ, and the counts converge to a steady ratio.
玩的时候该问的问题: 改变 k₁/k₋₁ 比值,平衡位置移到哪?为什么 k 值加倍并不改变平衡比,只是更快到达?(答案在 BoostChem U7) Change the k₁/k₋₁ ratio — where does equilibrium shift? Why does doubling both k's leave the ratio unchanged, only faster? (Answer: BoostChem U7)
