what system does reversible reaction need to occur in to reach equilibrium
closed
what type of reaction is equilibria
reversible reaction
when is equilibrium reached
when reactants occur at the exactly the same rate in each direction
what is le chateliers principle
if a dynamic equilibrium is disturbed by a change in conditions, the position of the equilibrium will shift to counteract that change
when concentration of reactants is increased, what happens to shift of equilibrium
shifts to the right - products
when concentration of products is increased, what happens to shift of equilibrium
shifts to left - reactants
if a reaction produces an increase in pressure, what happens to larger volume of gas ( more moles in products)
decreases yield of reaction - shifts equilibrium to left
if a reaction produces an increase in pressure, what happens to smaller volume of gas ( less in products)
increases yield of reaction - shifts right
if a reaction produces an decrease in pressure, what happens to smaller volume of gas ( less in products)
decreases yield of reaction - moves to the left
if a reaction produces an decrease in pressure, what happens to larger volume of gas ( more moles in products)
increase yield of reaction - shifts right
when temp is increased, equilibrium moves in direction of what
endothermic reaction
if temp is decreases, equilibrium moves in direction of.
exothermic
an increase in temp on an exothermic reaction, equilibrium moves..
left, decreases yield of reaction
a decrease in temp on an exothermic reaction, equilibrium moves..
right, increase yield of reaction
an increase in temp on an endothermic reaction, equilibrium moves
right, increase yield of reaction
a decrease in temp on an endothermic reaction, equilibrium moves
left, decreases yield of reaction
