Problem: The data below show the concentration of AB versus time for this reaction: Determine the order of the reaction and the value of the rate constant. Predict the concentration of AB at 25 s. 

FREE Expert Solution

For this problem, we will need to generate a set of graphs to answer this question. The graph that would generate a straight line is the order of the reaction.


The integrated rate law for a zeroth-order reaction is as follows:

[A]t=-kt+[A]0

y    =    mx   +  b

where:

[A]t = concentration at time t 
k = rate constant
t = time
[A]0 = initial concentration
