"barrier" nach Englisch mit Beispielen - Kollokationen-Wörterbuch Englisch
- The initial energy required is usually called an activation barrier.
- With enough energy to surmount activation barriers, however, the isomerization is usually very efficient.
- If there is a large activation barrier a spontaneous reaction may take a very long time to proceed.
- The activation barrier to give double carbonyl insertions is very high, so it does not occur.
- Scientists think that molecules need to get kicked over an "activation barrier" before they can break bonds and form new ones.
- Often chemical reactions require energy to overcome an activation barrier.
- The energy diverted to overcome these activation barriers is transformed into heat.
- Kinetically, there exists a low activation barrier to the decomposition reaction.
- In "through the barrier" models, a proton or an electron can tunnel through activation barriers.
- However, there is no large activation barrier if the reactants are in the first excited state.
