Chemical equilibrium

Question 1

what is dynamic equilibrium and when does it occur

Answer 1

when the forward rate is equal to the backwards rate in closed systems

Question 1

what is Le Chatelier’s principle

Answer 1

If a reaction at equilibrium is subjected to change in pressure, temperature for concentration the position of equilibrium will move to counteract the change
only works in homogenous equilibria

Question 2

if you increase conc of the products equilibrium will

Answer 2

shift to the left to use it up and more reactant is produced

Question 3

if pressure increases equilibrium

Answer 3

will shift to the side with the fewest number of gas particles

Question 4

if we increase temperature equilibrium will shift

Answer 4

in the endothermic direction

Question 5

if we decrease temperature equilibrium

Answer 5

will shift in the exothermic direction

Question 6

what is the Kc constant

Answer 6

Kc= products over reactants
exponents represent number of moles

Question 6

what effect do catalysts have on equilibrium

Answer 6

none
