Examples of reversible reactions include the following except:
__ is one which does not allow materials to either enter or leave.
Consider the following systems in equilibrium:
N2 (g) (1 mole) + 3H2 (g)(3 moles) ⇌ 2NH3 (g) (2 moles) ---------------------- (1)
For system (1):
A change in pressure affects the equilibrium positions of:
