Question

1.) 3RbI + AlF₃ <--> All₃ + 3RbF

2.) BeI₂ + BaF₂ <--> BeF₂ + BaI₂

3.) SrS + H₂0 <--> SrO + H₂S

Predict the direction in which the following reactions will proceed in. If possible, please explain your reasoning.

Answer 1

for all above three reactions (1,2,3 ) based on LE CHATELIER PRINCIPLE only.

according to his statement

a) if the concentration of reactants are increases , the equilibrium shift in right side of the reaction ,i.e forward reaction takes place

b)  if the concentration of reactants are idecreases , the equilibrium shift in left side of the reaction ,i.e backward reaction takes place

c) if the concentration of products are increases , the equilibrium shift in left side of the reaction ,i.e backward reaction takes place

d) if the concentration of products are decreases , the equilibrium shift in Right side of the reaction ,i.e farward reaction takes place

e ) if the pressure is increases , the equilibrium shift in direction to decrease in total number of moles side.

f) if the pressure is decreases , the equilibrium shift in direction to increase in total number of moles side.

g) with the increase the temparature endo thermic reactions takes place. with the decrease the temparature exo-thermic reactions takes place.
