Q:Effect of catalysts on reaction rate??
A catalyst provides an alternative route for the reaction, (maybe more steps than previously), but each step having a lower activation energy than the original uncatalysed reaction. This means that although there will be the same number of collisions per second (if the reaction is performed at the same temperature as before), a greater fraction of those collisions will result in a reaction - so there will be more reactions per second. In the case of a heterogeneous catalyst - e.g. a solid surface the change is that the first step is a bond to the surface which waekens some of the bonds in the reactants - again making a greater fraction of reactions result in reaction.
Q:What are the characteristics of the catalyst in the catalytic reaction?
The role of the catalyst in the chemical reaction is to change the rate of chemical reaction, and its own quality and chemical properties do not change.
Q:Chemical reaction in the presence of catalyst for the reaction are carried out a high life
Some reactions require some of the catalyst that is not needed
Q:What are the catalysts that appear in the chemistry experiment?
Hydrogen peroxide, manganese dioxide
Q:High school chemistry, catalyst activation energy map
Catalytic reaction is the reaction of the first reaction with the catalyst or attached to the catalyst to form intermediates, and then further reaction to produce products and catalysts, so the amount of catalyst in theory is the same! The activation of these two processes can be reduced! So there will be two peaks! Can be simplified as a peak!
Q:Is catalyst a metal or just a hard material?
a okorder.com/...
Q:Comparison of biocatalysts with chemical catalysts!
Differences: 1, the biocatalyst has a higher efficiency of the catalytic capacity; its efficiency is the general inorganic catalyst 10 of the power of 10 ~ 10 13 power.
Q:High school stage chemical catalyst
Manganese dioxide and iron are more common, vanadium oxide sometimes encountered, sulfuric acid is also a catalyst, but generally used as a dehydrating agent. Inorganic catalysts catalyze the object is diverse, unlike the organic catalyst as a single, so hard to say. In high school is probably used to prepare oxygen when the use of manganese dioxide
Q:Is the enzyme in the enzyme bigger than gold?
No: A biological enzyme is a biocatalyst that is produced or extracted from a biological organism. The catalyst is a substance that accelerates the chemical reaction and does not change itself in the chemical reaction. In layman's terms, the catalyst is a special substance that catalyzes it. Enzyme as a member of the catalyst family has its own special properties. Each of the biological enzymes will only selectively react to some chemical reactions.
Q:Could God be Discribed as a Catalyst?
Whether we agree with them or not, many people are driven by concept of god(even those trying to disprove god). So, yes, at least in part, 1 could describe god as a catalyst.
