SO2 + O2 <=> SO3
If the concentration of SO2 is increased, the equilibrium position of the reaction will shift ___________.
SO2 + O2 <=> SO3
If the equilibrium position shifts to the right, the concentration of O2 will ___________.
N2 + O2 <=> 2NO
If O2 is removed, the concentration of N2 will _______.
For the reaction...
N2 (g) + 3 H2(g) <=> 2 NH3 (g)
If the volume is decreased, which substance(s) will increase in concentration?
N2 (as 2 mol gas → 4 mol gas)
H2 (as 2 mol gas → 4 mol gas)
N2 and H2 (as 2 mol gas → 4 mol gas)
NH3 (as 4 mol gas → 2 mol gas)
For the reaction...
N2 + O2 <=> 2NO + 182kJ (the 182 kJ means heat)
If the temperature is increased the equilibrium position will shift _______.
to the left
to the right
to the left and right
neither left nor right
If a (dynamic) equilibrium is disturbed by changing the conditions, the position of equilibrium................
H2 (g) + Cl2 (g) <=> 2HCl (g) + heat
If the pressure in the system is increased, the equilibrium position will _______.
For the reaction...
N2 (g) + 3 H2(g) ⇌ 2 NH3 (g)
If the pressure in the system is increased, which substance(s) will increase in concentration?
N2
H2
N2 and H2
NH3
What is the effect of increasing the pressure on the following equilibrium: 2NO(g) + O2 (g) ⇌2NO2(g)?
The yield of NO2 increases
The yield of NO2 decreases
The reaction is slower
The concentration of O2 increases.
2SO2(g) + O2(g) ⇌ 2SO3(g)
Removing O2(g) will
shift equilibrium right
shift equilibrium left
increase pressure
have no change
2SO2(g) + O2(g) ⇌ 2SO3(g)
Adding SO3(g) will
shift equilibrium right
shift equilibrium left
increase K
have no change
H2(g) + Cl2(g) ⇌ 2HCl(g) + heat
What will happen to the equilibrium if the temperature is increased?
equilibrium shifts right
equilibrium shifts left
You cannot predict the effect
no change
