###### FREE Expert Solution

We’re being asked to calculate the overall order of this hypothetical reaction:

2A + B → products

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

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

We’re going to calculate the overall order for the reaction:
