dynamic equilibrium. Flashcards
define dynamic respiration.
if a reversible reaction is carried out in a closed container so that the reactants and products can’t escape a state of dynamic equilibrium can be established.
what is an example of dynamic equilibrium?
A+B ⇌ C+D.
why is the state dynamic in A+B ⇌C+D ?
both the forward and reverse reactions are ongoing
why is it in equilibrium A+B ⇌C+D ?
rates of the forward and reverse reactions are the same.
net concentrations of the components of the reaction mixture remain constant.
what is le chatelers principle?
if a factor affecting the position of an equilibrium is altered the new position of the equilibrium shifts to oppose the effect of the change.
A+B ⇌C+D.
if you add more A what will happen and why?
equilibrium will move to the right.
to decrease the amount of A.
A+B ⇌C+D.
what happens if you add more A+B?
equilibrium will shift to the right to decrease the amount of A+B and increase the amount of C+D.
A+B ⇌C+D.
if A+B were completely removed from the reaction what would happen?
C+D would react to make A+B.
equilibrium moves to the left.
which part of the arrow: ⇌ shows the direction for exothermic?
top.
which part of the arrow: ⇌ shows the direction endothermic?
bottom.
A(s) +B(aq) ⇌ C(aq) +D(g)
temp of vessel decreased.
-affect on C+D.
-affect on A+B.
-explain.
temp increased.
temp decreased.
exothermic is favoured.
A(s) +B(aq) ⇌ C(aq) +D(g)
temp of vessel increased.
-affect on A+B and C+D.
A+B: increase.
C+D: decrease.
