What is equilibrium?
Equilibrium is where the rate of forward reaction is equal to the rate of backward reaction and has no further tendency to change?
What happens when temperature increases?
Moves in direction of endothermic reaction to take in more heat energy and cool it down. Rate is increased.
What happens when temperature decreases?
Moves in direction of exothermic reaction to give out heat to surroundings, heating it up. Rate decreases.
What happens when pressure increases?
Moves in the direction of the fewest molecules of gas. Rate increased if reacting gases are present.
What happens when pressure decreases?
Moves in the direction of more molecules of gas. Rate decreases if reacting gases are present.
What happens when concentration of a reacting substance increased?
Moves in the direction away from the reacting substance. Rate increased.
What happens when concentration of a reacting substance decreases?
Moves in the direction towards the reacting substance. Rate decreases.
