WebAs a conclusion, a pseudo-first-order reaction mechanism was applied in all cases, with activation energies of 65.5–66 and 92.3 kj·mol −1 for KOH and CH 3 C 6 H 4 SO 3 H, respectively, proving the higher activation energy for acid catalysis compared to base catalysis. However, the process of synthesizing biodiesel with acid catalysts has ... WebEnzymes act as biological catalysts. The activation energy of reactions is lower when catalysts are used. The rate is faster if there's less activation energy for a react. Enzymes increase the speed of reactions by decreasing activation energy.
How does a catalyst affect activation energy? - KnowledgeBurrow
WebCatalysts can be used to lower the activation energy. The process of influencing chemical bonds to lower the activation energy of a reaction is called. catalysis. Students also viewed.

WebA catalyst must be regenerated in its original form for it to be considered as such. A catalyst is never consumed or produced by a reaction. At once, a catalyst cannot change the thermodynamic properties of a reaction, including the energy absorbed or released. Catalysts typically function by lowering the activation energy, not increasing it. cooking gloves disposable food safe
