Reaction Rates and Chemical Equilibrium
Terms in this set (16)
A state in which the rate of a forward reaction equals the rate of the reverse reaction. (There is a steady rate of concentration of reactants and products)
The study of reaction rates.
Unit of chemical reaction rate
A collision of molecules that results in a chemical reaction.
Activation energy and correct orientation of molecules
two things that are necessary for effective collision.
the minimum amount of kinetic energy between two molecules necessary for a reaction to occur.
Increase in concentration or temperature
Adds more molecules that can react
Gives alternate pathway for reaction to take place at a lower activation energy.
lowers activation energy
adding a catalyst does what to a reaction
In this type of reaction the energy of products is lower than the energy of the reactants.
In this type of reaction the energy of products is higher than the energy of reactants
Exact time at which the actual bonds are being broken and formed in a chemical reaction.
Homogeneous and heterogeneous
A catalyst can be either two types of substances
Definition of catalyst
any substance that increases the rate of a reaction without being consumed in the reaction.
A catalyst in a separate phase than that of the reactants.
A catalyst in the same phase as the reactants.
