The rxn between A and $B$ has been studied in a batch reactor at $25C.$ The concentrations at various times were as follow,

$\backslash$table$[[$follow;$,,,,],[t(min),0,5,33,8,17,15,13],[CB(mo\frac{l}{L}),0,099,0,0906,0,083,0,07],[CA(mo\frac{l}{L}),0,0566,0,0482,0,046,0,0282]]$

show that the $rn$ is $2^{nd}$ order and final rate constant.
