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.

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 … WebThinking, Fast and Slow is a 2011 book by psychologist Daniel Kahneman.The book's main thesis is a differentiation between two modes of thought: "System 1" is fast, instinctive … WebMulti-step (Consecutive) Reactions.
