Question
If the volume of a container (such as a piston) with NH3 gas, HF gas and solid
NH4F at equilibrium was decreased by a factor of two, you would expect that the
equilibrium pressure of HF gas after the change in volume would
NH4F (s) HF(g) + NH3(g) KP = 0.72 at 65 o
C
A. increase by a factor of 2 (double) since the volume decreases by a factor of 2.
B. increase but by less than a factor of 2 since the KP value is less than one.
C. decrease by a factor of 2 (go to half the original pressure) since the volume
decreases by a factor of 2.
D. decrease by less than a factor of 2 since the Dn value for this reaction is +2 and
decreasing the volume will favor the reactants.
E. come back to the same value as before but more solid NH4F would be formed.
