If the energy of the products is higher than the reactants, the reaction pathway is this type.
What is endothermic?
The amount of activation energy needed to start a reaction is lower in this type of energy pathway.
What is exothermic?
In order to react with one another, gas particles must do this.
What is collide?
Increasing the amount of reactant used, known as this, will increase the rate of the reaction.
What is concentration?
The change in reactant concentration per time in a reaction is a measure of this.
What is reaction rate?
This type of reaction rate indicates how fast a reaction is going at any one moment during the reaction.
What is instantaneous?
Providing an alternate pathway, the addition of this will lower activation energy and increase reaction rate.
What is a catalyst?
Without a sufficient amount of this, bonds cannot be broken or electrons removed so that new bonds can form.
What is energy?
The amount of energy the reactant particles have will go up, leading to a faster reaction rate, when you increase this factor.
What is temperature?
If the amount of product created is given in concentration, this will be the final unit for reaction rate.
What is mol/(L*s)?
Reaction rates tend to do this as time goes on.
What is decrease?
This is a temporary that is formed when activation energy is reached.
What is the activated complex?
Particles that collide must be facing each other in the correct direction, know as this, in order to create a product.
What is proper orientation?
By increasing the surface area of a reactant, we can do this to the rate of the reaction.
What is increase?
If 240 g of product are made in 2 minutes, this is the rate of reaction.
What is 2 g/s?
This type of reaction rate tells us on how fast a reaction occurs based on the total time that the reaction occurred.
What is average?
Once activation energy has been reached, a reaction can move forward to create products or do this.
What is reform reactants?
Increasing temperature will increase this, leading to a higher reaction rate.
What is the number of collisions (or the energy of the particles when they collide)?
Using oil instead of butter will change the rate at which cookies bake, which is an example of this factor.
What is nature?
What is 625 mL?
This type of catalyst is at a different state of matter than the reactants.
What is heterogeneous?
The gas in Bunsen burners does not combust as soon as you turn on the jet because you have not reached this.
What is activation energy?
Gases tend to react faster than solids or liquids because their motion is more this, causing them to collide more.
What is random?
A substance, such as oil, that can be used to stop or slow the rust and corrosion of metals is considered to be this factor.
What is an inhibitor?
If the rate for a chemical reaction is 0.5 mol/(L*s), this would be the time the reaction takes when starting with 10 mol of reactant.
What is 20 s?
