Seeing balance on a graph
- Plot the amounts over time and watch them level off.
- The curves flatten but never hit zero.
- A particle snapshot shows both reactants and products mixed.
- These pictures make the balance visible.
在图上看见平衡
- 把各种量对时间作图,看着它们趋于平稳。
- 曲线变平,但从不触及零。
- 一张粒子快照显示反应物和产物混在一起。
- 这些图把平衡变得可见。
Concentration-versus-time
- On a graph, concentrations change quickly at first, then flatten.
- The flat part is dynamic equilibrium 动态平衡, where amounts no longer change.
- The reactant and product curves both go horizontal.
浓度对时间
- 在图上,浓度起初变化很快,然后变平。
- 那平坦的部分是动态平衡,量不再变化。
- 反应物和产物的曲线都变成水平。
On a concentration-time graph, equilibrium is where the curves... · 在浓度-时间图中，平衡出现在曲线...
Flat curves mean the concentrations stop changing. · 曲线变平意味着浓度不再变化。
A particle snapshot
- A particle diagram at equilibrium shows both species present.
- Their numbers stay steady even as the reactions continue.
- The mix reflects the value of $K$.
粒子快照
- 平衡时的粒子图显示两种物种都存在。
- 即使反应继续,它们的数目也保持稳定。
- 这份混合反映 $K$ 的值。
A particle diagram at equilibrium shows... · 平衡时的粒子图显示...
Equilibrium mixtures contain both species. · 平衡混合物包含两种物种。
At equilibrium, the number of each kind of particle stays . · 平衡时每种粒子的数量保持。
Steady numbers reflect the balanced rates. · 稳定的数量反映了速率平衡。
What the pictures tell you
- A high product curve means a large $K$.
- Where the curves flatten tells you the equilibrium amounts.
- Both representations agree on the same balance.
这些图告诉你什么
- 高的产物曲线意味着大的 $K$。
- 曲线变平的位置告诉你平衡的量。
- 两种表示对同一份平衡意见一致。
A mixture at equilibrium · 处于平衡状态的混合物
Tap the particle box to see what stays constant at equilibrium. · 点击粒子框以查看平衡时保持不变的量。
A graph whose product curve levels off much higher than the reactant curve suggests... · 产物曲线远高于反应物曲线的图表表明...
More product at equilibrium means a large $K$. · 平衡时更多产物意味着较大的$K$。
On a concentration-time graph, what marks the moment equilibrium is reached?
- It is where the curves stop changing and go flat.
- After that point, the amounts hold steady.
在浓度-时间图上,什么标志着达到平衡的时刻?
- 它是曲线停止变化、变平的地方。
- 在那一点之后,各种量保持稳定。
At equilibrium the reactant concentration reaches zero. · 平衡时反应物浓度达到零。
Both reactants and products remain present. · 反应物和产物均存在。
A flat concentration line means there is no net change, not that reactions stopped. · 平坦的浓度线意味着没有净变化，而非反应停止。
The reactions continue at equal rates -- dynamic equilibrium. · 反应仍在以相等速率进行——动态平衡。
The curves flatten at equilibrium but do not reach zero -- both reactants and products remain. A flat line means no net change, not that the reactions stopped. And more product than reactant at the plateau signals a large $K$.
曲线在平衡时变平,但不会触及零——反应物和产物都仍然存在。一条水平线意味着没有净变化,而不是反应停止了。而且平台处产物多于反应物,提示大的 $K$。
Equilibrium looks like flattening curves on a concentration-time graph (a dynamic equilibrium where amounts stop changing but never hit zero) and like a particle snapshot with both species present. A high product plateau signals a large $K$; both pictures describe the same balance.
平衡在浓度-时间图上表现为变平的曲线(一种动态平衡,量停止变化但从不触及零),在粒子快照上表现为两种物种都存在。高的产物平台提示大的 $K$;两种图描述同一份平衡。
