WebCatalysts speed up chemical reactions. Only very minute quantities of the catalyst are required to produce a dramatic change in the rate of the reaction. This is really because the reaction proceeds by a different pathway when the catalyst is present essentially lowering the activation energy required for the reaction to take place. Webincreases the rate of a reaction does not alter the products of the reaction is unchanged chemically and in mass at the end of the reaction Only a very small mass of catalyst is needed...

WebA catalyst is a substance that: increases the rate of a reaction does not alter the products of the reaction is not chemically changed or used up at the end of the reaction Only a very... WebYes, if you increase the surface area of the catalyst, this will increase the rate of reaction. Concentration Experiment - Equation Na2S2O3 + 2HCl → 2NaCl + SO2 + S↓ (precipitate) + H2O What can be used to monitor the progress of the reaction? The formation of a yellow precipitate of sulfur can be used to monitor the progress of the reaction. cytopoint for dogs chewy

Solved QUESTION 4 How does a catalyst increase the rate of

WebSep 18, 2024 · A catalyst increases the rate of the reaction because: They provide an alternative energy pathway that has a lower activation energy This means that more particles have the activation energy required for the reaction to take place (compared to without the catalyst) and so the speed of the reaction increases. WebQuestion: How does a catalyst increase the rate of a reaction? O It makes the reaction more exergonic. It increases the temperature of the reaction. O It allows reacting molecules to more easily form the transition state. O It causes a localized increase in the concentration of reactants.
