What is the effect of adding the ZnCl2 catalyst to the already fast reaction of a tertiary alcohol with HX?
Adding ZnCl2 as a catalyst to the reaction of a tertiary alcohol with HX can enhance the reaction rate by facilitating the formation of the carbocation intermediate. Although the reaction is already fast due to the stability of tertiary carbocations, ZnCl2 can help stabilize the intermediate and improve the overall efficiency of the reaction. This results in a quicker conversion of the alcohol to the corresponding alkyl halide. Overall, the catalyst streamlines the process without altering the fundamental mechanism.

What parameter involved in a chemical reaction will change with the addition of a catalyst?
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.
What classification of alcohol undergoes oxidation to yield a ketone?
A secondary alcohol undergoes oxidation to yield a ketone; a primary alcohol forms an aldehyde instead, and a tertiary alcohol usually does not form either a ketone or an alcohol, because the carbon having the OH group in a tertiary alcohol already has three bonds to other carbon atoms and therefore cannot form a double bond to oxygen without more extensive breaking of other bonds in the tertiary alcohol.
Why catalyst does no react with the reactants?
A catalyst is something that speeds up the reaction by providing a more suitable environment for it to occur, but is itself not consumed in the reaction. The simplest answer would be that if it reacted, then by definition, it would be another reactant and no longer considered only a catalyst. The reason the catalyst is not affected can vary, but it could be because it's already in a stable form, stable enough not to be affected with the reactants.
What happens when you mix rubbing alcohol and glue?
There is no reaction, you simply get a mixture of rubbing alcohol and methanol.
How is the cracking reaction made faster?
Cracking is a process used in chemistry to break large molecules .It is also called pyrolysis . It produces small molecular wt. compounds . Most chemical reactions are increased by temp, it is already exothermic hence there is no need to enhance it , it would become dangerous and resultant molecules would change. Hence it is not proper to make it faster .

How would the equilibrium concentration of H2O be affected by adding a catalyst to the mixture?
Adding a catalyst to the mixture would not affect the equilibrium concentration of H2O. A catalyst speeds up the rate of the forward and reverse reactions equally, without changing the position of the equilibrium. This means that the equilibrium concentration of H2O would not be affected by the presence of a catalyst.

Does alcohol increase a drivers reaction time?
Yes, when your mind has been effected by alcohol it tends to slow your thought process down. Surely you know this already.

Can alcohol be melted?
Alcohol is already molten.
Why is the Cretaceous - Tertiary period also called the K-T period?
K = Cretaceous (C is used for another era already) T = Tertiary
What does a tertiary care hospital mean?
Tertiary in general means third. In a medical context, it could be found in a few uses. The tertiary phase of a disease is the third phase; for example, neurosyphilis is hte tertiary phase of that disease. Tertiary care is highly specialized hospital care. For instance, a burn center or trauma center might be a tertiary care center - a place to which other hospitals transfer patients for more specialized care. Tertiary prevention is concerned with helping people who are already ill to improve their quality of life and minimize disability.
What if you burn methane and methyl alcohol which gives off more heat?
Methane gives off more heat. Burning something is an oxidation reaction. Energy is released by forming more and more bonds between carbon and oxygen. Since methyl alcohol already has a C-O bond, it is already more oxidized than methane, so burning methyl alcohol releases less energy (heat) than burning methane (mole for mole).
What is the effect of increasing the concentration of enzymes in a reaction?
If the reaction speed has not already peaked, then it will increase
How a catalyst increases the rate of a reaction?
There are two ways in which catalysts work. You already know that when two different molecules bump into each other, they might react to make new chemicals. We usually talk about "collisions" between molecules, it would be much simpler to say that the molecules bumped into each other. How fast a chemical reaction is depends upon how frequently the molecules collide. You have probably been told about the "kinetic theory" which is all about heat and how fast molecules move around. What catalysts are doing when they make a chemical reaction go faster is to increase the chance of molecules colliding. The first method is by "adsorption", the second method is by the formation of intermediate compounds.Adsorption This occurs when a molecule sticks onto the surface of a catalyst. Make sure that you spell this word correctly; it is not the same as absorption. Here is an example: it is possible to use Platinum as a catalyst to make sulphur Trioxide from Sulphur Dioxide and Oxygen. Sulphur Trioxide is very important because it is used to make Sulphuric acid which is needed for car batteries. The molecules of the two gases (Sulphur Dioxide and Oxygen) get adsorbed (stuck onto) the surface of a Platinum catalyst. Because the two molecules are held so close together, it is more likely that they will collide and therefore react with each other. The Sulphur Trioxide easily falls off the catalyst leaving space for more Sulphur Trioxide and Oxygen.Intermediate Compounds Many catalysts, including all enzymes" work by forming intermediate compounds. What happens is very simple: the chemicals involved in the reaction combine with the catalyst making an intermediate compound, but this new compound is very unstable. When the intermediate compound breaks down it releases the new compounds and the original catalyst.
