Question 1

What does it mean if Qc is higher than Kc? How about lower?

Answer 1

Higher means that reverse reaction is favoured, lower means that forward reaction is favoured

Question 2

At a spontaneous reaction what are the gibs and entropy values

Answer 2

Gibs is lowest and entropy is highest

Question 3

How does reversing and changing coefficents of equilibrium equation affect kc

Answer 3

1) new kc is reciprocal
2) if coefficents doubled, kc squared

Question 4

For gibbs free energy equation answer should be in what?

Answer 4

kJ so you have to divide 8.31/1000

Question 5

Ice Table coefficents what do you put for concentration?

Answer 5

+/- x but in front of x coefficent

Question 6

Which factor does NOT affect vapour pressure of liquid in equilibrium

Answer 6

Volume of container and liquid, these changes will cause the vapour to readjust the equilibrium, so does NOT affect

Changes in temperature increase kinetic energy

Question 7

Why would adding dilute solution instead of concentrated in esterification affect yield?

Answer 7

Dilute adds water which is a product

Question 8

What equilibrium constant corresponds to a spontaneous reactionwith the most negative value of G?

Answer 8

highest Kc
