1. A reaction is in equilibrium, and then due to a T increase, a forward shift is favoured. Which of the following would definetely NOT have changed?
total moles
total mols and total mass
total mass
total concentration
2. The following is in equilibrium.
N
2
+ 3H
2
↔ 2NH
3
If the pressure is increased by decreasing the volume, how will the following change if T constant?
mols of N
2
/ conc of N
2
increase / increase
decrease / decrease
increase / decrease
decrease / increase
3. The following is in equilibrium.
N
2
+ 3H
2
↔ 2NH
3
Now inert Argon gas is injected into the system, increasing the pressure. What effect would this have on the equilibrium?
forward shift
no effect.
reverse shift
forward shift, then a reverse shift
4. The volume is increased in this equilibrium: 2A(g) + B(g) ↔ 3C(g)
What happens to the shift / reaction rate / conc
increase/decrease/unchanged
unchanged/decrease/increase
unchanged/unchanged/unchanged
unchanged/decrease/decrease
5. Study this equilibrium:
N
2
+ 3H
2
↔ 2NH
3
A forward shift can be created by increasing the pressure:
on the left hand side only
on the right hand side only
on the left hand side, and decreasing pressure on the right hand side
of the system
