Question

For which of the following reactions will an increase in pressure not effect the position of equilibrium?


2A2 (g) + B2 (g) 2A2B (g)

2AB (g) A2 (g) + B2 (g)

2A (g) + F2 (g) 2AF (g)

2B (s) + 2HA (aq) 2BA (aq) + H2 (g)

Answer 1

you're name sounds like catholic just saying lolz :)

Answer 2

probably the last reaction. i deduced this because the first 3 involve gas reactions (which change in pressure) and the last one isn't involving a gas (except hydrogen gas)

Answer 3

Yes last one as for pressure to effect the equilibrium all species should be in gas form.

Answer 4

It's the 2nd reaction:
\[2AB(g) \rightleftharpoons A_2(g) + B_2(g)\] both sides have 2 mols of gas. A reaction will shift in response to pressure only when there is a difference in the moles of gas product. All the other reactions have a change in the number of moles of gas.
