###### FREE Expert Solution
• 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
