The Rate and Extent of Chemical Change

Question 1

what is le chateliers principle

Answer 1

the idea that if you change the conditions if a reaction at equilibrium, the system tries to counteract the change
- can be used to predict the effect of any changes you make to a reaction system

Question 2

what would the effect be of decreasing the concentration of an equilibrium

Answer 2

• the system tries to increase it again by reducing the amount of REACTANTS

Question 3

what would the effect be of increasing the concentration of an equilibrium

Answer 3

• the system tries to decrease it again by making more PRODUCTS

Question 4

Answer 4

-

Question 5

Answer 5

-

Question 6

Answer 6

-

Question 7

what would the effect be of increasing the pressure of an equilibrium

Answer 7

-

Question 8

what does it mean if a system is at equilibruim

Answer 8

• forward and reverse reactions happen at the same rate

Question 9

what does the position of the equilibrium depend on

Answer 9

temperature
pressure (gases only)
concentration
