Problem: Under certain conditions the decomposition of ammonia on a metal surface gives the following data:Determine the rate equation, the rate constant, and the overall order for this reaction.

FREE Expert Solution

We’re being asked to determine the rate equation, the rate constant, and the overall order for the reaction based on the reaction and data given.


Recall that the rate law only focuses on the reactant concentrations and has a general form of:

rate law=kAxBy

k = rate constant
A & B = reactants
x & y = reactant orders


We will calculate the rate order first. Since we only have one reactant, we can use any of the data interval given:

rate 2rate 1=NH3x at rate 2NH3x at rate 1

x = order
