If Q> K then the reaction shifts to?
reactants...left
If Q is smaller than K than the reaction shifts to?
Products...right
K
p
=?
Kp=Kc(RT')
n
Does a large equilibrim constant ensure that a reaction will take place if there are only reactants are present
No! the rate can be so slow that no product is formed
Thermodynamic control?
concentration ofproducts and reactants depends on relative stabilityof the species?
Kinetic control?
concentration of products andreactants depends rates of reaction (i.e. k and Ea)
Qc= 0
pure reactant
Qc= infiniy
pure products
Qc=Kc
equillibrium
How does a catalyst change the reaction?
It doesnt only affects the rate
When the volume of an equilibrium mixtureof gases is reduced, a net change occurs inthe direction that produces ______moles ofgas
fewer
When the volume is increased, a netchange occurs in the direction that produces______ moles of gas.
more
