equilibrium Flashcards
(9 cards)
in a reversible reaction when is equilibrium reached
when the concnetration of reactants and products is constant
When are chemical reactions in a state of equilibrium
when the rate fo the forward reaction equals the rate of the backwards reaction
At equilibrium whats the concentration of reactants compared to products
usually different
What happens at equilibrium
concentrations of reactants and products remain constant but are rarely equal
What does a catalyst do
increases the rate of the forward and reverse reaction equally
What is bond enthalpy
the energy required to remove one mole of bonds in a molecule
State what is meant by the term dynamic equilibrium
The rate of the forward reaction
equals the rate of the reverse
reaction.
What is represented by the area under a kinetic energy graph
the total number of particles
Pressure has no effect on the position of the equilibrium suggest what this shows about the states of both chemicals
They are not in a gaseous state
