Zero Order Reaction

  • In a zero order reaction, the rate of reaction is independent of the concentration of the reactant.

  • The rate equation for a zero order reaction is rate = k, where k is the rate constant.

  • The half-life of a zero order reaction is given by t1/2 = [Ao]/2k, where [Ao] is the initial concentration of the reactant.



Decomposition of NH3 on Platinum Surface

  • The decomposition of NH3 on a platinum surface is a zero order reaction.

  • This reaction produces nitrogen gas (N2) and hydrogen gas (H2).



Rate of Production of N2 and H2

  • The rate of production of N2 and H2 can be calculated using the rate equation for a zero order reaction: rate = k.

  • Since the reaction is zero order, the rate of production of N2 and H2 is constant and equal to the rate constant (k).

  • Therefore, the rate of production of N2 and H2 is given by: rate of N2 = rate of H2 = k = 2.5 ×10 to the power -4.



Explanation

  • The decomposition of NH3 on a platinum surface is a well-known reaction in chemistry.

  • This reaction is important because it is used in the production of nitrogen and hydrogen gases, which are essential for many industrial processes.

  • The reaction is zero order because the rate of reaction is independent of the concentration of NH3.

  • This means that the rate of production of N2 and H2 is constant and equal to the rate constant (k).

  • The rate constant (k) is a measure of how fast the reaction occurs.

  • In this case, k is given as 2.5 ×10 to the power -4, which means that the reaction occurs relatively slowly.

  • However, the reaction is still useful because it allows for the production of nitrogen and hydrogen gases in a controlled and efficient manner.
