# 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:

$\overline{){\mathbf{\left[}\mathbf{A}\mathbf{\right]}}_{{\mathbf{t}}}{\mathbf{=}}{\mathbf{-}}{\mathbf{kt}}{\mathbf{+}}{{\mathbf{\left[}}{\mathbf{A}}{\mathbf{\right]}}}_{{\mathbf{0}}}}$

y    =    mx   +  b

where:

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