Solution: For the equation,2 H2 (g) + X2 (g) ⇌ 2 H2X (g) + energyi) Write the equilibrium constant expression.  ii) Addition of argon to the above equilibrium a) will cause [H2] to decrease.                    


For the equation,

2 H2 (g) + X2 (g) ⇌ 2 H2X (g) + energy

i) Write the equilibrium constant expression.



ii) Addition of argon to the above equilibrium 

a) will cause [H2] to decrease.                      b) will cause [X2] to increase.

c) will cause [H2X] to increase.                     d) will have no effect.

e) cannot possibly be carried out.



iii) Increasing the pressure by decreasing the volume will cause 

a) the reaction to occur to produce H2X.

b) the reaction to occur to produce H2 and X2.

c) the reaction to occur to produce H2 but no more X2.

d) no reaction to occur. 

e) X2 to dissociate.
