Question

Given the system at equilibrium: H2(g) + F2(g) 2 HF(g) + heat Which change will not shift the point of equilibrium?D) changing the concentration of HF(g)B) changing the temperature C) changing the concentration of H2(g) A) changing the pressure

Answer 1

The answer is A.

Changing the pressure will NOT shift the point of equilibrium.

Because there is no change in the total number of molecules in the system during reaction, a change in pressure does not favor either formation or decomposition.
