Now lets’s substitute this expression into our three integrated rate law equations. Rate expressions describe reactions in terms of the change in reactant or product concentrations over the change in.
Integrated Rate Law Graphs. Time data and must be graphically. Then the [b] is changed, but is still present in excess.

Chem 142 experimen t #5: 1 [ a] t = k t + 1 [ a] 0 y = m x + b. Using the differential rate law, a graph of concentration versus time is a curve with a slope that becomes less negative with time, whereas for the integrated rate law, a graph of ln[reactant] versus time gives a straight line with slope = −k.
Rate expressions describe reactions in terms of the change in reactant or product concentrations over the change in time. Then the [b] is changed, but is still present in excess. • analyze graphs of data to determine best linear fit. The effect of this change will give the order of the reaction with respect to b.

The integrated rate law allows you to calculate the concentration of a reactant at any time during the reaction; Rate = k[a]a [b]b but since [b] doesn’t really change, this becomes rate = k’[a]a where k’ = k[b] the results can then be analyzed using the integrated rate laws. • create and use a calibration curve for the absorbance/concentration relationship.
