WebUsing catalysts leads to faster, more energy-efficient chemical reactions. Catalysts also have a key property called selectivity, by which they can direct a reaction to increase the amount of desired product and reduce the amount of unwanted byproducts. They can produce entirely new materials with entirely new potential uses. WebBy decreasing the particle size of a reactant, we are increasing its surface area. The greater the surface area, the higher the chance of collisions, thus the faster the rate of reaction. The...

WebIncreasing the concentration of the enzyme, however, would increase the absolute number of reactions occurring simultaneously; thus, the rate of reaction (but not the rate constant) would increase.

Therefore, increasing substrate concentrations at this phase does not affect the reaction rate since it is maximum.

WebSome students may believe that the catalysts – especially the oxides – are reactants because hydrogen peroxide is not noticeably decomposing at room temperature. The teacher could point out the venting cap on the peroxide bottle as an indication of continuous slow decomposition. WebA catalyst is a substance that speeds up a chemical reaction, or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction. Catalysis …

WebCatalysts increase the rate of reaction without being used up. They do this by lowering the activation energy needed. With a catalyst, more collisions result in a reaction, so the rate of reaction increases. What are the 4 factors that affect reaction rate?
