1) The following equilibrium exists between ethane (C₂H₆), ethene (C₂H₄₎ and hydrogen (H₂):

C₂H₆ ⇌ C₂H₄ + H₂

We insert 8 mol of C₂H₆ in the reaction chamber, which is initially empty. After a while equilibrium is established and we find that there are 3 mol of C₂H₄ in the chamber (equilibrium concentration).

How many mol of C₂H₆ and H₂ exist at equilibrium?

 

a) 2 mol C₂H₆ e 3 mol H₂

b) 3 mol C₂H₆ e 3 mol H₂

c) 4mol C₂H₆ e 1 mol H₂

d) 5 mol C₂H₆ e 3 mol H₂
