lower activation energy, make the reaction more economical
A catalyst is a substance that speeds up the rate of a chemical reaction without changing the substance. It does this by reducing the minimal reaction energy. A catalyst is not used up in a reaction therefore they last indefinitely.
A catalyst speeds up the rate of a chemical reaction by lowering the activation energy needed for the reaction to occur. In the case of an enzyme-catalyzed reaction, the enzyme serves as a biological catalyst, allowing the reaction to occur more efficiently and at lower energy levels than it would without the enzyme.
A catalyst increases the rate of a chemical reaction by providing an alternative pathway with lower activation energy. This allows for more reactant molecules to overcome the energy barrier and form products more quickly, without being consumed in the process.
The opposite of a catalyst is an inhibitor, something that suppresses or slows a reaction.
That would be a catalyst.
It's called a catalyst. A catalyst is present during a chemical reaction but does not participate as a reactant or product. A catalyst lowers the reaction's activation energy, making the reaction easier to happen. In the equation for a chemical reaction, the catalyst's formula appears in small notation above the "yield" arrow (format won't let me show you an example.) An example of a catalyst is potassium iodide (KI) speeding up the decomposition of hydrogen peroxide (H2O2).
Yes - but biological catalyst would be an even better description.
a catalyst provides a different path for a reaction to occur To lower the activation energy of a reaction
Catalyst. Biological catalysts would be enzymes.
Increasing temperature, increasing concentration of reactants, and adding a catalyst are all factors that can increase the rate of a chemical reaction. This is because they either provide more energy for the reaction to occur (temperature), increase the frequency of reactant collisions (concentration), or lower the activation energy required for the reaction to proceed (catalyst).
The reagent needed to complete a reaction depends on the specific reaction being carried out. It could be a catalyst, solvent, substrate, or a specific chemical compound required for the reaction to proceed successfully. Consulting the reaction mechanism or the experimental protocol would help identify the necessary reagents.
That would be an enzyme. Also know as a biological Catalyst
