rates of reaction/chemical equilibrium definitions Flashcards
(6 cards)
1
Q
rate of reaction
A
the rate of reaction is the change in concentration of any reactant or product per unit time
2
Q
catalyst
A
a catalyst is a substance which alters the rate of reaction but is not used up in the process
3
Q
activation energy
A
the activation energy is the minimum amount of energy required for a reaction to occur
4
Q
chemical equilibrium
A
chemical equilibrium is a dynamic state in which the rate of the forward reaction is equal to the rate of the reverse reaction
5
Q
dynamic state
A
dynamic state means that it is in constant motion
6
Q
le chatelier’s principle
A
le chatelier’s principle states when a stress is applied to a system at equilibrium the system adjusts to remove the stress applied
