Chemistry Definitions Flashcards
To understand and know the definitions in CAPE Chemistry (5 cards)
1
Q
State the definition of the ‘Le Chatelier’s Principle’
A
Le Chatelier’s principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change to reestablish an equilibrium.
2
Q
State Hess’s Law
A
Hess’s Law states that the total enthalpy change during the complete course of a chemical reaction is independent of the route taken.
3
Q
Dynamic Equilibrium
A
A system is in dynamic equilibrium when the rate of the forward reaction is equal to the rate of the backward reaction in a reversible reaction.
4
Q
State Avogadro’s Law
A
Avogadro’s Law states that equal volumes of ideal gases at the same temperature and pressure contain the same number of particles
