Question

Hydrogen chloride can be made from the reaction of chlorine and hydrogen:

Cl2 (g) +H2 (g) → 2HCl (g) 

For this reaction, K = 26 x 1033 and ∆H = - 44 kcal/mol at 25C

Is the reaction exothermic or endothermic?

 

Are the reactants or the products favored at equilibrium?

Explain the effects on the equilibrium of:

Increasing the pressure by decreasing the volume

 

Increasing the concentration of Cl2 (g)

 

Increasing the concentration of H2 (g)

 

Decreasing the concentration of HCl (g)

 

Increasing the temperature

 

Adding a catalyst
