What are the 2 reasons why a decrease in temperature slows a chemical reaction?
Decreasing the temperature reduces the kinetic energy of the molecules involved. This means that fewer molecules have the activation energy required to actually react. It also means that molecules will collide less often.
How do reactants and products participate in a chemical reaction?
Reactants are the starting materials that undergo a chemical change to form products. During a chemical reaction, reactant molecules collide and undergo chemical transformations to produce new molecules known as products. The reactants are consumed, while the products are formed as a result of the reaction.
What increase is the chance of a reaction when two molecules collide?
pressure
What are 3 conditions that necessary for a reaction to occur?
There are many factors that affect the occurance of a chemical reaction. If the reaction you are using has any buffer or catalyst than you should be selective in that keeping in mind your reactants and product. The temperature required for any particular reaction to occur should also be kept in mind.
What is the effect on the rate of a chemical reaction when the concnetration of a reactant is decreased?
Decreasing the concentration of a reactant will typically decrease the rate of a chemical reaction, as there are fewer reactant molecules available to collide and form products. This is in line with the rate law, which often shows a direct relationship between reactant concentration and reaction rate.
Do molecules need to collide for a chemical reaction to occur?
Yes, it is true.
What effect does raising the temperature of a chemical reaction?
Raising the temperature of a chemical reaction typically increases the rate of the reaction as it provides more energy for the molecules to react. This is because a higher temperature increases the kinetic energy of molecules, allowing them to collide more frequently and with greater force, leading to more successful collisions and faster reaction rates.

The reactants are consumed, while the products are formed as a result of the reaction.
Explain what a coefficient in a balanced chemical equation represents?
The coefficients in a chemical equation represent the amount of moles of each substance involved in the reaction. On a smaller level, it also represents the amount of particles that have to collide or are produced in the reaction. Consider the following example: CH4(g) + 2O2(g) (arrow) 2H2O(l) + CO2(g) The coefficent behind oxygen in the reactants means that 2 molecules of oxygen have to collide with 1 molecules of methane to react. The coefficients in the products mean that this reaction produces 2 molecules of water and 1 molecule of carbon dioxide.

How does the proximity effect impact the chemistry between molecules in a reaction?
The proximity effect in chemistry refers to how close molecules are to each other during a reaction. When molecules are closer together, they are more likely to collide and interact, leading to a higher chance of chemical reactions occurring. This can impact the chemistry between molecules by increasing the rate of reaction and potentially changing the products formed.
Will Increasing the rate at which particles collide will increase the rate of a reaction?
Yes, increasing the rate at which particles collide will generally increase the rate of a reaction. This is because more collisions between particles lead to a higher likelihood of successful reactions taking place.
