WebMar 4, 2024 · When given a two chemical reactions, and we know that one is slow and the other is fast, the problem should either give us clues to determining which is which. For example, the problem could say that the equilibrium constant (k1) of one reaction is slower than the equilibrium constant (k2) of the other reaction. WebWhat happens when the first step in a multi-step reaction is not the rate-limiting step? Consider the reaction between NO and O 2 to form NO 2, for example. 2 NO(g) + O 2 (g) 2 NO 2 (g) This reaction involves a two-step mechanism. The first step is a relatively fast reaction in which a pair of NO molecules combine to form a dimer, N 2 O 2. lodges in whitley bay https://search-first-group.com

Activation energy (article) Khan Academy

WebYes, there are negative catalysts which slow down chemical reactions. These don't work by raising the activation energy (because, if they did, the reaction would simply proceed by the uncatalysed route which has a lower activation energy). Instead, they either work by reacting catalytically with intermediates, thus breaking the reaction chain, or else by … WebIn general, the transition state of a reaction is always at a higher energy level than the reactants or products, such that E A \text E_{\text A} E A start text, E, end text, start subscript, start text, A, end text, end subscript always has a positive value – independent of whether the reaction is endergonic or exergonic overall.
