Problem: For the reaction A ⟶ B + C, the following data were obtained at 30 °C:(a) What is the order of the reaction with respect to [A], and what is the rate equation?

FREE Expert Solution

We’re being asked to determine the order of the reaction with respect to [A], and what is the rate equation 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=Ax at rate 2Ax at rate 1

x = order
