Consider the reaction represented by the following equation: N2(g) + 3H2(g) ⇌ 2NH3(g); ∆H = – 92kJmol1. Finely divided iron is used as catalyst in the reaction in order to

  • lower the value of ∆H
  • increase the time for attainment of equilibrium
  • shorten the time for attainment of equilibrium checkmark
  • decrease the yield of ammonia

The correct answer is: C
