  • Overall order can be calculated by determining the sum of orders of each reactant. 

  • Rate law relies on the concentrations of the reactants where:

  • Rate law for the reaction will appear as:

  • For the reactant order, we must look for the data where the concentration of one changes while the other remains constant.

  • Calculating order with respect to NH3
