The rate of a reaction increases if:
· The temperature is increased
· The concentration of a dissolved reactant is increased
· The pressure of a reacting gas is increased
· Solid reactants are broken into smaller pieces
· A catalyst is used

What does the rate law tell you about a reaction?
How the concentration of the reactants affects the rate of a reaction
How does agitation effect reaction rate?
Agitation affects reaction rate by increasing the amount of collisions the atoms make with one another, therefore speeding up the reaction rate.
How does an increase in concentration affects rates of chemical reaction?
The rate of chemical reaction increase as the concentration of the chemicals increase. The reason is obvious. There is more opportunity for the atoms to come in contact with each other. This facilitates rate of chemical reaction.
What is the method for the disappearing cross experiment?
the disappearing cross method is a method used when observing how the concentration of a chemical affects the rate of reaction.
What happens to the reaction rate as the reactants get used up in a reaction?
The rate of a reaction begins to decreases as reactant are used up
What does the rate law tell you about a reaction?
How the concentration of the reactants affects the rate of a reaction
What does the rate law tell you about the reaction?
How the concentration of the reactants affects the rate of a reaction
Which factor affects the reaction rate by altering the reaction path?
catalyst
which of the following affects the rate of constant of a reaction?
The temperature of the system
How does temperature affects the rate of industrial reaction?
It depends. A higher temperature will speed up an endothermic reaction, but slow down an exothermic reaction.
How does agitation effect reaction rate?
Agitation affects reaction rate by increasing the amount of collisions the atoms make with one another, therefore speeding up the reaction rate.
Is it true that when an enzyme promotes a chemical reaction by lowering the activation energy it only affects the rate of the reaction?
yea
What is a change that affects chemical reaction rate?
Factors affecting the reaction rate:- Concentrations of the reactants- Temperature- Pressure- Sirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
How does an increase in concentration affects rates of chemical reaction?
The rate of chemical reaction increase as the concentration of the chemicals increase. The reason is obvious. There is more opportunity for the atoms to come in contact with each other. This facilitates rate of chemical reaction.
How does temperature affects reaction rate?
if the reaction is exothermic (creates heat) then adding heat will cause the reaction to run in the reverse direction if the reaction is endothermic (requires heat) then heat will speed it up
Which is not a factor that affects the rate of a reaction?
Force of gravity. The temperature of Mars. The number of ships in the harbour. The weight of a penny.
A factor that affects the rate of reaction?
There are several factors that affect the rate of reaction: -The surface area available. -Temperature -Availability of catalyst. -Concentration, if a/the reactant(s) is/are solutions. -Pressure, if a/the reactants(s) is/are gases. -Reactivity of reactants. -Activation energy of the reaction.
