What are 4 things that can affect the rate of a reaction?
1. Temperature: Depending on the temperature of the reactants, the reaction rate will differ. The higher the temperature (or the hotter the reactant is), the quicker the reaction will occur. The cooler the reactant is, the longer it will take for a reaction to take place. The heat causes the particles to move quickly, and due to the Collision Theory, which states that in order for a reaction to occur, molecules must collide, the particles will be more likely to bump into each other, and so the reaction will occur faster.2. Concentration: The higher the concentration of a reactant, the quicker the reaction will occur. This means that there are more particles of that particular substance, meaning it will collide more frequently into the particles of the other reactant. This increases the reactant rate because the more concentrated a reactant is, it means that the less space there is between the two reactants.3. Surface Area: Basically, the more particles that are exposed during the experiment, the faster the reaction will occur. The more the particles are exposed, the faster it is for the other reactant to collide into the particles, meaning the reaction rate will increase.4. Catalysts: Catalysts are substances that increase the rate of reaction by speeding up the reaction without being used up in the reaction. It does not affect the reactants in any other way than making them collide into each other more frequently, and it doesn't affect the product (or products) produced
What would increase the concentration of reactants?
It means that there will be more particles of the reactants in the vessel, so they are more crowded and collisions of the right energy are more likely. or collisions of the right energy are more likely.
How does the concentration of affect the rate of reaction?
It increases the rate of reaction because there are more particles so they are more likely to collide
What change will most likely increase the rate of a chemical reaction?
Factors which can increase the rate of a chemical reaction:- temperature- pressure- concentration of reactants- stirring- if solids are involved the dimension of particles is important- the type of reaction- the order of reaction- presence of catalysts- influence of external factorsetc.
What is the product of the reactant HCl plus AlOH3?
It depends on how and where the reaction takes place. Aluminium chloride is unstable in the prescence of water and reacts to give a variety of hydroxy-chlorides or hydroxide, or hydrated complex salts. With no water present, there is likely to be a complex salt formed.

Increasing the temperature of the system increases the in the system making it more likely that two particles will collide with thereby increasing the?
average kinetic energy, enough energy, reaction rate
What would increase the concentration of reactants?
It means that there will be more particles of the reactants in the vessel, so they are more crowded and collisions of the right energy are more likely. or collisions of the right energy are more likely.
Do reactions slow down if there diluted?
yes because the particles are less likely to collide
If the temperature of a chemical reaction is increased the reaction rate?
It depends if the reaction is endothermic (requires heat/energy) or is exothermic (requires no heat/energy and produces heat/energy). In general, most reactions are endothermic and require some amount of energy to 'go' and hence, an increase in temperature will increase the rate of reaction. However, in exothermic reactions, introducing heat can halt the reaction as well as reverse it, if said reaction is reversible.
How does the concentration of affect the rate of reaction?
It increases the rate of reaction because there are more particles so they are more likely to collide
The equilibruim constant is the ratio of product concentration to reactant concentration at equilibruim A reaction will likely go to completion if the equilibrium constant?
a} Is very high.
Why do faster moving particles increase the rate of reaction?
The particles need to come in contact for the reaction to take place, normally. If the particles move at faster rate, they are more likely to come in contact with each other. That makes the reaction to take place faster.
Increasing the concentration of a substrate substance slows down the rate of reaction?
No, if you increase the concentration of a substance there is a more likely chance of particle collisions occurring. Meaning the higher the concentration the faster the rate of reaction. Imagine people walking around in an empty room, the more people there are in the room, the more likely it is that they will begin to bump into each other, it's the same with particles. The bumping into each other (or collisions) is what will increase the rate of reaction. Conversely if you lower the concentration, there is a lot less chance that the tiny particles will collide with one another meaning the rate of reaction will decrease. Hope this Helps!
What occurs in a reaction in which the reactant is a solid and the product is a gas?
the answer is D. AS most likely would be positive because a gas has a greater entropy than a solid.
What factors make reaction go faster?
Because at higher temperatures, there is more energy in the reactants. With more energy, they move faster. This makes them more likely to collide, causing a chemical reaction. This also results in more energy at the impact, making it easier and more likely that the reactants achieve the activation energy required for the reaction to happen. Also, in decomposition reactions, there is more energy available to complete the reaction, and the "binding states" of the reactants are under more stress (so they are easier to "break").
Why does freezing temperature generally increase the rate of a chemical reaction?
Consider kinetic theory. Since heat is the rapid movement of particles, the more temperature there is, the more movement. If the particcles in a chemical reaction are moving constantly, they are much more likely to collide and react with one another.
