Its a inhibitor.Science worksheet? I just finished it! Lol
A Catalyst.
Catalyst
what would most likely result in the greatest decrease in the rate of a chemical reaction
In general, and depending on the order of the reaction, the rate will decrease as the reaction progresses.
decrease the energy requirement of reaction, which increase the rate of reaction itself
The concentration of the reactants decreases.
Either (or both) an increase in the reactants or temperature will increase the rate of a chemical reaction.
In general, a material that decreases the rate of a chemical reaction is called an inhibitor.
Inhibitor~a material used to decrease the rate of reaction
retardant
what would most likely result in the greatest decrease in the rate of a chemical reaction
The time the reaction takes increases.
inhibitor
An inhibitor decreases the reaction rate
negative catalyst.
A catalyst speeds up the rate of reaction, and lower the activation energy needed.
For most reactions, the lowering of the temperature of the reactants.
It will increase the rate of the reaction because more particles will be exposed and they will be able to react.This decreases the time to react.
It depends entirely on the particular reaction. See the Related Questions link for more about reaction rates.
