Problem: The graph below shows a plot of the rate of a reaction versus the concentration of the reactant A for the reaction:A → products .Estimate the value of k.

FREE Expert Solution

We’re being asked to calculate the rate constant with the correct units for the given reaction. We can calculate the rate constant of the reaction from its rate law.


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

Problem Details

The graph below shows a plot of the rate of a reaction versus the concentration of the reactant A for the reaction:

A → products

 The figure shows the rate of a reaction as a function of the concentration of the reactant. Rate is measured from 0 to 0.012 moles per second on the y-axis, and the concentration is measured from 0 to 1 mole on the x-axis. The curve is a straight line which starts at the intersection of the axes and goes to 1 mole at the rate of 0.01 moles per second..

Estimate the value of k.
