Question

2. Le Chatelier’s Principle:

If the reaction below is at chemical equilibrium, what would happen to the equilibrium position if the stresses below were applied?    

 

heat + CH4(g) + 2 H2S(g)  ⇆  CS2(g) + 4 H2(g)

a) CH4(g) is added

_____________________________________________________________________

b) removal of H2S(g)

_____________________________________________________________________

Answer 1

a) CH4(g) is added: the equilibrium will shift to the right producing more product

b) H2S(g) is removed: the equilibrium will shift to the left to produce more reactant
