Question
  1. Consider the following equilibria:

 

Equilibrium I: H2O(g) + C(s)                                     H2(g) + CO(g);             ΔH = +131 kJ mol-1

2-

 

(
 

Equilibrium II: Cr2O4- aq)  + 2H+(aq)                                    Cr2O7

 

(aq)  + H2O(l)

 

 

Use Le Chatelier’s principle to predict and explain the effect of:

 

  1. increasing the pressure on Equilibrium I.
  2. increasing the temperature on Equilibrium I.
  • increasing [H+] on Equilibrium II.
  1. the presence of a catalyst on Equilibrium II.
