Concentrated sulfuric acid is generally used to promote acid-catalyzed dehydration because:
ira [324]
Concentrated  sulfuric  acid  is  used    to promote  acid  catalyzed  dehydration  because  it  has   little  water.This favor the  forward  reaction.sulfuric  acid  acts  as  as  proton  source  to  enable  loss  of  leaving  group  in  forward  reaction  and electrophile  addition  in  reverse  reaction.

B. The equilibrium constant for the reaction 2H2(g) + S2(g) 2H2S(g) is Keq = . (3 points)
eimsori [14]

Answer:

i. Keq=4157.99.

ii. More hydrogen sulfide will be produced.

Explanation:

Hello,

i. In this case, for the concentrations at equilibrium on the given chemical reaction, the equilibrium constant results:

Keq=\frac{[H_2S]^2}{[H_2]^2[S_2]} =\frac{(0.97M)^2}{(0.051M)^2(0.087)} =4157.99

ii. Now, by means of the Le Chatelier's principle, the addition of a reactant shifts the reaction towards products, it means that more hydrogen sulfide will be produced in order to reach equilibrium.

Best regards.
