Question 1

For 2A(g)  B(g) at equilibrium: 
Add A:

Answer 1

System consumes A, reaction shifts right

Question 2

For 2A(g)  B(g) at equilibrium: 
Remove A:

Answer 2

System produces A, reaction shifts left

Question 3

For 2A(g)  B(g) at equilibrium: 
Add B:

Answer 3

System consumes B, reaction shifts left

Question 4

For 2A(g)  B(g) at equilibrium: 
Remove B:

Answer 4

Reaction produces B, reaction shifts right

Question 5
