We’re being asked to determine the rate law 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’re going to calculate the rate law and the rate constant using the following steps:

Problem Details

Kinetic data for the following reaction were determined experimentally: 

A + B → 2 C

What is the rate law for the reaction?

A. rate = k•[A]1•[B]2

B. rate = k•[A]1/2•[B]5

C. rate = k•[A]2•[B]1

D. rate = k•[A]1•[B]1/5

E. rate = k•[A]1/2•[B]2
