Reaction rates

英语例句库

However,using THEIC initiator,the reaction rate for epichlorohydrin is faster than that of propylene oxide and 2-butoxyxirane,respectively.

在THEIC体系,就链引发而言,环氧氯丙烷的大于环氧丙烷、丁基醚环氧乙烷。

The gas-solid reaction mechanism was studied in the tank reactor.It was found that the reaction rate was controlled by the interdiffusion and intrinsic chemical reaction.

在釜式反应器内研究了氯磺化反应的气固相反应机理,发现气体的内扩散和本征化学反应是氯磺化反应的控制步骤。

少年谢尔顿 第四季

In fact, I noticed a flaw in your reaction rates, but I kept it to myself because I know my place.

事实上,我注意到你的反应速率有错误,但我绝口不提,因为我懂得守本分。

化学 Crash Course

So the reaction rate, that's the rate at which the concentrations of the reacts decrease and this has to be determined experimentally.

所以反应速率,即反应浓度降低的速率,这必须通过实验确定。

SciShow 合集

But right now, with so much ocean acidification, the natural reaction rates are way too slow to help neutralize all this extra acid.

但现在,由于海洋酸化程度如此之高,自然反应速度太慢,无法帮助中和所有这些额外的酸。

化学 Crash Course

Once the energy requirements are met the reaction will proceed, but its speed, or reaction rate, will vary wildly from super fast to super slow.

一旦满足能量需求, 反应就会继续进行,但它的速度或反应速率会从超快到超慢变化很大。

化学反应速率 Reaction rate

(重定向自Reaction rates)

反应速率即化学反应进行的快慢,单位为mol/(L·s)或mol/(L·min)。用单位时间内反应物的浓度的减少或生成物浓度的增加量来表示。浓度单位一般用莫耳·升,时间单位用秒、分或小时。化学反应并非均匀速率进行:反应速率分为平均速率(一定时间间隔里平均反应速率)和瞬时速率(给定某时刻的反应速率),可通过实验测定。反应物本身的性质,外界因素:温度,浓度,压强,催化剂,光,激光,反应物颗粒大小,反应物之间的接触面积和反应物状态,x射线,γ射线,固体物质的表面积,与反应物的接触面积,反应物的浓度也会影响化学反应速率。

Reaction rate 化学反应速率

(重定向自Reaction rates)
Iron rusting has a low reaction rate. This process is slow.
Wood combustion has a high reaction rate. This process is fast.

The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example, the oxidative rusting of iron under Earth's atmosphere is a slow reaction that can take many years, but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second.
