As far as I know, No. A negative order means a higher concentration of the reactant having a lower reaction rate. For example: concentration of A reaction rate ---- 4 M .1 M/s 1 M .4 M/s ---- rate1/rate2=k(A1)n/k(A2)n k canceled (.1M/s)/(.4M/s)=(4M/1M)n 1/4=4n n=-1 but the reaction rate is usually proportional to the concentration of the reactant, which means reactants with a higher concentration have a greater reaction rate, in a few case, increase the concentration of reactant have little effect for the reaction rate. So, the order of the reaction is usually positive in a few case, it's close to 0. For more information about the relationship between reaction rate and the concentration of recants check out: http:/en.wikipedia.org/wiki/Reaction_rate http:/www.chemguide.co.uk/physical/basicrates/concentration.html

∙ 14y agoMy general chemistry text reads that the exponents which determine rate order 'are generally small, positive integers, but they may be negative or occasionally non-integral.' It does not list examples, however.

When a catalyst is added to a reaction?
There are positive catalysts used when the reaction rate is needed to be faster or the negative catalysts to make the reaction rate slower.
What is the material that slows down the rate of a chemical reaction?
negative catalyst.
What is a material that slows down the rate of a chemical re action?
In general, a material that decreases the rate of a chemical reaction is called an inhibitor.
How does the present of a catalyst affect the rate of reactions?
A catalyst is a substance which speeds up the rate of reaction. After the reaction it remain chemically unchanged. It does NOT affect the position of equilibrium. There can also be negative or "poisoned" catalysts as in Rosenmunds reaction.
What measures of how fast reaction occurs?
The measure is the rate of reaction.

What is the material that slows down the rate of a chemical reaction?
negative catalyst.
Differentiate a positive catalyst from a negative catalyst?
A positive catalyst is a catalyst which speeds up the rate of a chemical reaction by lowering its activation energy. A negative catalysts slows the rate of a chemical reaction or makes it less likely to occur.
What is a material that slows down the rate of a chemical re action?
In general, a material that decreases the rate of a chemical reaction is called an inhibitor.

What measures of how fast reaction occurs?
The measure is the rate of reaction.
What is the speed at which a reaction occurs called?
The chemical term is reaction rate.
What is the difference between positive catalyst and negative catalyst?
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.
What describes a reaction that reaches equilibrium?
The product and reactants reach a final, unchanging level.
What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
Could heat increase the rate of reaction?
if reaction is exothermic then on heating rate of reaction wil be low,and if reaction is endothermic then rate of reaction wil be high on heating
What is the rate of the of a reaction?
An expression relating the rate of a reaction to the rate constant and the concentrations of the reactants
