$AB+C$

is carried out in a constant$-$volume batch reactor, and concentration of reactant $(C{A}_A)$ is measured as a

function of time. The following data are obtained:

a$.$ Use the integral method for determining rate laws to construct plots assuming orders $0,1,$ and $2$ for

this reaction such that the plots would be linear $($as we demonstrated in class$).$ Is the data consistent

with any integer order, and, if so$,$ which order?

b$.$ Use nonlinear regression to fit $CA0,k,$ and $$ simultaneously.

c$.$ The technician who carried out these experiments expresses concern that there may have been an

error in the measurement at $t=60$min. Based on your fits and comparison with the data, is this

likely? Repeat your fitting procedure in b$.$ without the data point at $60$min $($assume we are able to

reject this data as an outlier$).$ What fitting values do you obtain for this updated fit?
