Question
Workshop 11: Kinetics part 2 (A graphical analysis) By now you know that thermody namics helps s to predict whether or not a process will be spontaneous at given conditions and kinetics s us whether r not a thermodynamically allowed process wi ll actually p roceed at a measurable rate under these conditions. The rate at s determined by its activation energy, E. Activ which a reaction will proceed on energy can ate an otherwise spontaneous chemical reaction so that it defined as the energy necessary will continue to react without the need for additional energy. (For example burning paper reaction ulose and is spontaneous, but you need initiate the adding activation energy from a lit match]. can analysis to determine the a n energy of a chemical reacti nformation about n form of graphs to obtai n this workshop we will use ex perimental results kinetics of two chemical processes Part 1: In tegrated rate laws graph and without ealculation answer the Before you write down your make sure that agrees with them is a partial ree of pressu a) with your group how this graph can help you to de reaction, what the order of this reaction? Explain your choice. etermine the order of the b) What is the k value for this reaction (make sure to include units)?
Explanation / Answer
a)For a first order reaction, a plot of lnP versus time (t) is a straight line with slope –k
Hence it is a first order reaction.
b)Slope = -k = - (-1.19 x 10-4) ..(value is not clear in the box. Please check)
k=1.19 x 10-4
