How is a catalysts different from a reactant?

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process, while a reactant is a substance that participates in a chemical reaction and is consumed. Essentially, a catalyst speeds up a reaction without being changed itself, while a reactant is consumed during the reaction.


What is a catalyst only used in photosynthesis?

Chlorophyll is the catalyst that is used in the process of photosynthesis.


Is sodium hydroxide a reactant?

If NaOH is totally used up in the reaction process, it is a reactant; If not it's a catalyst.


Is sugar a reactant or a product?

Sugar can be both a reactant and a product, depending on the chemical reaction. For example, in the process of photosynthesis, sugar (glucose) is produced as a product. However, in the process of fermentation, sugar is a reactant that is broken down to produce other products like ethanol and carbon dioxide.


Why is light not a reactant or a product?

Light is not a reactant or a product in a chemical reaction because it does not undergo a chemical change. While light can provide the energy needed to drive certain reactions (such as photosynthesis), it is not consumed or produced in the process.


In photosynthesis is chlorophyll considered a reactant or a product?

Chlorophyll is actually a catalyst, an enzyme that facilitates the chemical reaction but is not changed by the reaction. When writing the photosynthesis equation out, the word 'chlorophyll' is often written over the "yields" arrow to indicate "in the presence of chlorophyll yields".


Is a catylist a product reactant or neither?

A catalyst is neither a product nor a reactant; it is a substance that accelerates a chemical reaction without being consumed in the process. It facilitates the reaction by lowering the activation energy required, allowing reactants to convert to products more efficiently. After the reaction, the catalyst remains unchanged and can be used again.


What is a sentence using the word catalyst?

"A sparking wire was the catalyst in the natural gas explosion." "Chlorophyll is the catalyst in the process of photosynthesis."


Describe the roles of a catalyst and substrate in a chemical reaction?

A catalyst is a substance that speeds up the rate of a chemical reaction. Catalysts work by lowering a reaction's activation energy.A substrate is a reactant of an enzyme-catalyzed reaction.


What is a reactant in the general photosynthesis equation?

In the general photosynthesis equation, carbon dioxide (CO2) is a reactant. It is used by plants, algae, and some bacteria in the process of photosynthesis to produce glucose and oxygen in the presence of sunlight.


Is the catalyst consumed in the reaction process?

In a chemical reaction, a catalyst is not consumed and remains unchanged at the end of the reaction process.


Does photosynthesis involve a physical or chemical change?

Photosynthesis involves a chemical change.
