Do catalyst work better in hot or cold water?
Most of us may familiar with hotter the better but it is not necessary that catalyst prefer hot temperature. Catalyst do provide alternative path with lower activation energy, and it is not necessary like heat if the trend of overall reaction is exothermic. Many catalyst work best on limited range of temperature not too high and not too low.
How does an iron catalyst affect the rate of reaction?
All first row/period transition metals, iron included, are good catalysts. They provide a surface on which the reactants can briefly adhere, thereby slightly altering the electronic energies/ arrangements. This allows the other reactant to react quicker, thereby the electronic arrangements change again and the new molecule detaches from the catalytic surface. NB Catalysrs speed up a reaction. and Inhibitors slow down a reaction.
Of what adaptive value is the alternative pathway of respiration in plants?
Respiration in plants is essential to provide metabolic energy and carbon skeletons for growth.! MOKAZ WAZ HERE!=D
How does enzymes speed up chemical reactions?
The way enzymes speed up chemical/biochemical reactions is the same way that catalysts work. They provide an alternate pathway for the reaction which has a LOWER activation energy. They don't actually decrease the activation energy of the pathway in question, but rather they provide a different pathway that has a lower energy of activation.
Is ATP a catalyst?
No, they simply provide the energy for the reaction to occur. Specific enzymes are the catalysts, as they are the ones to lower the Ea of the reaction and use the energy from ATP --> ADP + Pi. These processes are often exergonic and irreversible.
Why catalyst affect the rate of chemical reaction?
They provide alternative pathway for the reaction, usually with less energy barrier
How enzymes works?
Provide an alternate pathway with a lower activation energy for a reaction
What name is given to a solution that does not participate in a visible reaction?
Catalyst? They dont exactly participate in a reaction, just provide an alternate pathway with a lower energy barrier.
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.)

Why are catalysts spread out in a reaction?
Catalysts are chemicals that alter the rate of a chemical reaction without being chemically changed themselves . However to alter the rate of the reaction , the catalysts need to come in contact with the reactant particles. Spreading out the catalyst increases its surface area , hence increases the chances of coming in contact with the reactant particles . So they are able to provide the reactant particles an alternative route with a lower activation energy for the reactant particles to collide and form the product .
Why does a catalytic converter have a honeycomb structure?
Because honeycomb structure provide large surface area to the exhaust gasses for reaction under the action of catalyst then any other structure.
How is the rate of a reaction influenced by a catalyst?
The rate of reaction often increases when catalysts are added. Catalysts can either lower the activation energy required for the reaction to happen, so that means more molecules will have enough energy to react than if the activation energy were higher. Catalysts can also be like substrates that act as a site for holding the molecules in the correct position to react. Always remember that molecules need to collide in the correct position with enough energy in order to react, and so catalysts will aid these two requirements and increase the reaction rate. There are catalysts that slow the reaction, but it's not common.
