You mean in a chemical equation?
There it is always written over the arrow. Like so:
.........electricity
2H2O------------>H2+O2
A catalyst is something that speeds up a reaction without being consumed itself. The classic example is Manganese dioxide as a catalyst in the decomposition of hydrogen peroxide.
change the speed of the reaction without undergoing in it
A catalyst is used to increase the rate of a chem reaction.
Catalyst is a compound which helps in lowering the required temperature for the reaction to take place in lower temperatures. Catalyst can be different for different reactions.
the catalyst can be included in the reactants side of the equation or written above the arrow to indicate its presence in the reaction.
One way is to write it above the arrow that links reactants going to products.
it is shown by a yield sign
A catalyst can improve the reaction rate or allows the realization of a chemical reaction with an energy lower than the activation energy.
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
Adding a catalyst a chemical reaction can occur with a lower activation energy.
A catalyst.
With a catalyst the reaction rate is higher.
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.
No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
Adding a catalyst a chemical reaction can occur with a lower activation energy.
A catalyst.
A catalyst doesn't undergo a chemical change during a chemical reaction.
* Reactants: the initial compounds in a chemical reaction. * Products: the final compounds in a chemical reaction. * Catalyst: a chemical compound which help the chemical reaction but not react with the other compounds.
With a catalyst the reaction rate is higher.
A catalyst alters the rate of a chemical reaction.
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
