Question 1

What is the general formula of K

Answer 1

K = conc. of products to the power of their stoichiometry/

conc. of reactants to the power of their stoichiometry

Question 2

if K <1, then log10 K<0 …..

Answer 2

The equilibrium lies on the left

Question 3

What does it mean if the equilibrium lies more to the left

Answer 3

There’s more starting material

Question 4

if K = 1, then log10 K = 0:

Answer 4

The equilibrium is even

Question 5

What does it mean if the equilibrium is even

Answer 5

there’s equal amounts of both complexes

Question 6

if K > 1, then log10 K > 0:

Answer 6

The equilibrium lies on the right

Question 7

What does it mean if the equilibrium lies onto the right

Answer 7

That there’s more product

Question 8

What does K indicate

Answer 8

Where the equilibrium lies

Question 9

the higher the k value the ….

Answer 9

more thermodynamically favourable the forward reaction is

Question 10

What does the conc. of M,ML,ML2 depend on

Answer 10

[M] total and [L]

Question 11

3 things about a speciation diagram

Answer 11

often more than 3 species present
Horizontal axis is normally L
[ML]2 becomes major species at high L
