WebOct 1, 2024 · For a chemical reaction: a A + b B → p P + q Q. The rate of the reaction is: r = k (T) [A] n [B] n. k (T) is the rate constant or reaction rate coefficient. However, this value is not technically a constant because it includes the factors that affect reaction rate, most notably temperature . n and m are reaction orders. WebFor example, consider a multi-step reaction :- A + B → C + D Step 1 (Slow Step):- A + A → C + E (Rate constant, K1 ) Step 2 (Fast Step) :- E + B → A + D (Rate constant, K2 ) Here E is an intermediate, the product in step 1 and a reactant in step 2 that does not show up in the overall reaction. WebSep 7, 2024 · What is reaction order AP Chem? In order for a reaction to occur effectively, reactant molecules must be moving with sufficient energy, and they must collide in the proper orientation. Reactions involving gaseous reactants occur faster compared to liquid or solid reactants. Having aqueous reactants also affects the reaction rate. iphone 4 pro max case
