English Dictionary

activation energy

名詞

(chemistry, physics) The energy required to initiate a reaction. For example, the flame from the fuse of a firecracker provides a small initial amount of energy, after which the explosive reaction proceeds by itself, releasing a considerably larger quantity of energy. A small push given to a stable but top-heavy object may cause it to fall over; the potential energy released during the fall was present in the system all along but could not be realized as long as the object was upright and balanced.

日本語の意味

化学反応や物理現象において、反応を開始するために必要な最小限のエネルギー

To model the reaction rate, the team measured the activation energy and then introduced a catalyst to lower the barrier.

反応速度をモデル化するために、チームは活性化エネルギーを測定し、その障壁を下げるために触媒を導入した。
