Predict the direction of the equilibrium shift for each of the following process

Question

Predict the direction of the equilibrium shift for each of the following processes: a. H_2 (g) + CI_2 (g) 2 HCI (g) What direction will the equilibrium shift when the partial pressure of hydrogen is increased? b. 3H_2 (g) + N_2 (g) 2 NH_3 (g) Given that this reaction is exothermic, what direction will the equilibrium shift the temperature of the reaction is decreased? c. 2 NO_2 (g) N_2 O_4 (g) If a large quantity of argon is added to the container in which this equilibrium is taking place, in what direction will the equilibrium shift? d. NH_4 OH(aq) NH_3 (g) + H_2 O (I) In what direction will the equilibrium shift if ammonia is removed from the container as soon as it is produced? e. 2 BH_3 (g) B_2 H_6 (g) If this equilibrium is taking place in a piston with a volume of 1 L and I compress it so the final volume is 0.5 L, in what direction will the equilibrium shift?

Explanation / Answer

1)

a) H2 (g) + Cl2 (g) <------------> 2 HCl (g)

if the partial pressure of H2 increases , then the equilibrium shifts to forward direction .

b)

3 H2 (g) + N2 (g) <---------------> 2 NH3 (g)

for exothermic reaction , temperature decreases then the equilibrium shifts to forward direction.

c)

no shift

d)

equilibrium shifts to forward direction
