How a catalyst speeds up a reaction
WebA catalyst speeds up the rate at which a reaction reaches dynamic equilibrium. Example 3 You might try imagining how long it would take to establish a dynamic equilibrium if you took the visual model on the introductory page and reduced the chances of the colors changing by a factor of 1000 - from 3 in 6 to 3 in 6000 and from 1 in 6 to 1 in 6000. WebWhich statement best describes how a catalyst can speed up a chemical reaction? The catalyst decreases the activation energy needed. The catalyst increases the concentration of products. The catalyst binds to enzymes to release substrates. The catalyst increases the concentration of reactants. a. The catalyst decreases the activation energy needed.
