  1. Equilibrium In Chemical Reaction

  2. N2 + 3H2 2NH3 The double arrow tells us that this reaction can go in both directions:

  3. N2 + 3H2 2NH3 1) Reactants react to become products, N2 + 3H2 2NH3 (‘forward’ reaction)

  4. N2 + 3H2 2NH3 1) Reactants react to become products, N2 + 3H2 2NH3 (‘forward’ reaction) while simultaneously, 2) Products react to become reactants N2 + 3H2 2NH3 (‘reverse’ reaction)

  5. N2 + 3H2 2NH3 In a closed system, where no reactants, products, or energy can be added to or removed from the reaction, a reversible reaction will reach equilibrium.

  6. N2 + 3H2 2NH3 At equilibrium, the rateof the forward reaction becomes equal to the rate of the reverse reaction, and so, like our escalator metaphor, the two sides, reactants and products, will have constant amounts, even though the reactions continue to occur.

  7. N2 + 3H2 2NH3 However (like the metaphor), the equilibrium amounts of reactants and products are usually not equal, they just remain unchanged.
