simple equilibria and acid based reactions

Question 1

reversible reactions

Answer 1

as reactions form products, the products can turn back to reactants at the same time
endothermic in one direction (absorbs heat so the solution feels cool)
Exothermic in the other direction (gives off heat)

Question 2

Dynamic equilibrium

Answer 2

-The rate of the forward reaction is equal to the rate of the back reaction
-Appears as if nothing is changing but the atoms are constantly interacting
-must occur in a closed environment

Question 3

position of equilibrium

Answer 3

Describes the equilibrium state achieved under a certain set of conditions

Question 4

Amount of products and reactants

Answer 4

More reactants= the reaction moves to the left (forward reaction)
more products= the reaction moves to the right (reverse reaction)
