This law states that in a chemical system there is constant ratio between products and reactants
Chemical Equilibrium?
This will favour the endothermic reaction.
An increase in temperature.
The name of the smallest country in the world.
Vatican City
What happens to the concentration of the reactants and products in equilibrium?
Constant
This stress only affects equilibrium reactions with at least one gas
Pressure changes
At equilibrium the reactions at macroscoptic level appear to have ________ BUT are still ________ at a microscopic level.
stopped, dynamic/occurring
What is the difference between enthalpy and exothermic?
Enthalpy = overall energy change, exothermic = energy released.
This addition of this will speed up BOTH the rate of the forward AND reverse reactions.
What is a catalyst?
What does pressure not affect in equilibrium? (3 states)
Solids, Liquids, Aqueous solutions
Fe3+ + SCN- <------> FeSCN2+ If I added Fe3+ to the system the reaction would favor....
Products
2 NOCl(g) < -----> 2 NO(g) + Cl2(g) If NOCl(g) was removed from the system, the concentrations of NO(g) and Cl2(g) would ___i___ and the equilibrium constant would ___ii___.
Decrease, remain the same?
An increase in pressure (decrease volume) will favor the side with the---------amount of molecules
Least?
Graph drawn with 2 lines.
increase in temp line = faster rate, same vol of products
N2O4 <---> 2NO2 (+ 58.0 kJ)
In order to favor the products the temperature would need to...
Decrease
What are the magic words for explaining reaction rates at equilibrium. Give me 3 phrases.
Favours, shifting of equilibrium, successful collisions, moles, per unit volume
