When writing a chemical equation, an arrow pointing up would indicate that a gas is going to bubble out of the solution. An arrow pointing down indicates that some product will precipitate out of the solution.
up arrows represent gas and down arrows represent precipitates
In a chemical equation, the arrow means yields. For example: H2CO3----> CO2+H2O. Do you get it?
The up arrow is used on the products side of a reaction to show that a compound is released as a gas.
In the chemical equations the up arrow means the "product is a Gas".
The up arrow in a chemical reaction symbolizes the evolution of a gas. Similarly, the down arrow symbolizes precipitation.
to slow down a chemical reaction you use the substance called an inhibitor. to speed up a chemical reaction you use the substance called a catalyst.
Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
Catalysts speed up the chemical reaction.
A catalyst is a substance that accelerates a chemical reaction. It does this by lowering the activation energy necessary for that reaction to start. A catalyst is not a reactant or a product, and it does not get used up in a reaction. It is simply present with the reactants and the products and it does not change in a reaction. In an equation, it is correct to show the chemical formula for the catalyst in small characters above the "yield" arrow. The opposite of catalyst is inhibitor.
Energy that starts a chemical reaction is called activation energy
The enzyme is written above the arrow of the chemical equation because it is involved in the reaction without being changed by it or used up in the reaction. It is not a reactant or a product.
A catalyst can speed up a chemical reaction.
It reads as "Yields." The equation is set up as (reactants) (Yield Sign) (Products).

to speed up a chemical reaction
to slow down a chemical reaction you use the substance called an inhibitor. to speed up a chemical reaction you use the substance called a catalyst.
Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
Activation energy is lowered to speed up a chemical reaction.
Chemical reactions can be sped up by: 1) Increasing the surface area of reaction. 2) Heating the reaction. 3) Sometimes choosing a different solvent can speed things up. 4) Use of a catalyst.
to speed up a chemical reaction .. we use a catalyst
Decrease the activation energy to speed up a chemical reaction.
Catalysts speed up the chemical reaction.
