What are the 4 ways to increase the speed of a chemical reaction?

Rate Enhancements in organic chemistry can be achieved by:
i) Increasing the molecular contact between substrate and reagent
ii) Increasing the local effective concentration
iii) Increasing the reactivity of the reagent or substrate i.e. increasing the rate constant (this may arise by an increased interaction between reaction partners)
iv) Preferentially stabilizing the transition state on the normal reaction path
v) Changing the mechanism to one which has a lower energy transition state

∙ 12y agoThe 4 basic ways are
- Temperature : increasing temperature increases molecular activity
- Concentration : a concentrated solution will have more interaction
- Surface Area : a larger surface means more reactants come in contact
- Catalysts : by making intermediary reactions, catalysts speed the eventual result
A 5th way is often the simplest: Stirring - mixing the reactants so that more of the reactants come in contact for a given concentration, and products are moved out of the way.

decrease for exothermic reactions).
2-Change in pressure (for gaseous reactions only) or
Increase in surface area of reactants.
3-Increase in concentration of reactants.
4-Use of a catalyst.

What speeds up in chemical reaction?
There are numerous ways to affect the speed of a chemical reaction. They are add a catalyst, increase the concentration of reactants, increase surface area of reactants, increase pressure, and increase the energy in the environment around the reaction.
Why do different metals react in different way and with different speed?
The way of reaction depends on its type, and the metal. As for the speed, there are different ways to increase or decrease reaction rate(temperature, catalyst.)
Name two ways to speed up a reaction?
increasing surface area addition of a catalyst
What are three ways to increase the rate at which particular reaction proceeds?
There are three ways to increase the rate of a chemical reaction. One way is to increase the temperature of the reaction, which increases the rate of molecular collision. Another option is to add a catalyst to the reaction which chemically enables the rate of reaction. Lastly, increase the pressure in the reaction area, which increases the rate of molecular collisions.

Which will speed up a chemical reaction A Apply heat B Increase the concentration of the reactants C Grind up the substance so there is more surface area?
The 2 ways to increase chemical reaction rate are applying heat or a catalyst. So it is A : Applying heat. ;)
What are two ways the speed of a chemical reaction can be increased if both of the reactants are aqueous solutions?
It can be done with those substance which remains as it was before the reaction but increases the speed of the reaction.
What are Ways to change the rate of a chemical reaction?
1. Increase the temp 2. Increase surface area 3. Increase the pressure of the system

What methods can you use to increase the rate of a chemical reaction?
There are several ways that the rate of reaction may be increased. Some of the more common ways areincrease temperatureincrease surface area (grind or powder the reactants)use a catalystagitate/stir the reaction mixture
What is one way to speed up a chemical reaction besides adding enzymes?
Two ways: Add heat Add pressure
One of the ways that enzymes speed chemical reaction is?
They are organic catalysts. All catalysts will speed up a reaction by lowering the activation energy of the reaction, or the energy required to break certain atoms apart so that they can be reformed to make new products.

Lastly, increase the pressure in the reaction area, which increases the rate of molecular collisions.
What are the 4 ways to increase the speed of a chemical reastion?
- Changing temperature (heating increases speed of endothermic reactions and such reactions with a huge activation energy; cooling increases speed of exothermic reactions - Adding a catalyst (makes the activation barrier smaller --> reaction faster) - Vary the pressure. If there are less equivalents of gas molecules on product site than on educt site, pressure increase will increase reaction speed and vice versa. - Changing concentration; if the educt concentration is increased or / and product concentration decreased (e.g. through destillation of the product), the reaction will go faster. --> These four principles can found in the Le Chatelier - Sentence. Nice example is the Haber-Bosch synthesis.
Do catalysts speed up a chemical reaction or slow it down?
A catalyst works by providing a reaction route with a lower activation energy. An inhibitor slows a reaction and can work in several ways, for instance by tying up one of the reactants. We also use the term when we say catalyst inhibitor, which is something which binds to the active sites on a heterogeneous catalyst.
