Name for any substance that speeds up the rate of chemical reaction?
A substance that speeds up a chemical reaction is known as a CATALYST.
Use catalyst in a sentence?
A catalyst is a substance that causes or aids in any type of reaction. Here are some sentences.That enzyme words as a catalyst in your body.She was the catalyst that started the argument.A catalyst is needed to make this chemical reaction occur.
Define catalyst to a catalyst?
A catalyst is a substance that accelerates or increases the rate of a chemical reaction. In principle a catalyst should remain unaffected during the process. However normally it loses some activity during it resuses.
What ia a catalyst?
A Catalyst provides an alternate and less complicated pathway or route for reactants to form products in a reaction. An effect of a catalyst is the speeding up or slowing down of the rate of a chemical reaction.It should not be confused with Promoter, which increases the efficiency of a catalyst.
The primary function of an enzyme or any biological catalyst is to?
The primary function of an enzyme or any biological catalyst is to increase the rate of a chemical reaction by lowering the activation energy barrier, thereby facilitating the conversion of substrate molecules into products. This process allows cells to efficiently carry out metabolic reactions necessary for growth, maintenance, and energy production.
What are catalysts and what do they do?
Catalyst is a a substance that raises the rate of a chemical reaction without necessarily experiencing any any permanent chemical change.
Does a catalyst decrease the speed of a reaction?
A catalyst lowers the activation energy of a chemical reaction without undergoing any change in mass but may change in color , texture e.t.c <a href="http://linkjacket.com/jk.cgi?i=rMkA9ue&d=www.kentchemistry.com&n=NaN" target="_self">visit kentchemistry.com</a> it can also speed up a reaction. simply a catalyst can change the rate of a reaction, both slow and increase rate
What are situations that can effect the rate of a chemical reaction?
In a typical chemical reaction, xA + yB --> zC, the rate can be expressed as: Rate = k (T) * [A]^x * [B]^y where k = Rate constant, a function of temperature [i] = molar concentration of reagent i So, chemical reaction rate is affected by temperature and reagent concentration. Thus any variable that affects temperature (e.g. pressure or volume in the case of gases) will also affect reaction rate. However, the rate constant k is also a function of activation energy, the energy required to drive the reagents to the point where the reaction must proceed to completion. This activation energy can be lowered by the presence of a catalyst. Thus the presence of a catalyst can also affect the reaction rate.
The role of a catalyst?
A catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction. basically it increases or decreases the speed of a chemical or biological reaction, but it does not get itself involved in the reaction. hoped this helped (:
What is the substance called that increases the rate of reactions in living systems?
A catalyst is any chemical that speeds up a chemical reaction. It does this by lowering the activation energy required for the reaction to take place. A catalyst that occurs in an organism is called an enzyme.
How do catalyst affect a chemical reaction?
Adding a catalyst will make the reaction happen faster because the catalyst makes the Activation Energy (the energy required for the reaction to take place) to lower. Meaning more molecules can acquire this lower number of energy. A chemical reaction that involves a catalyst is a special type. A catalyst, in a given chemical reaction, is something that is both an input *and* an output of the reaction equation. What that means, practically, is that a small amount of catalyst is enough to process any amount of the other inputs. (More catalyst means that a given amount will be processed faster.)
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
