Explanation / Answer

Q1

we must find the fit with a straight line, so

from th elist, 1/[A] vs t is the best fit

this is typical for a 2nd order reaction

then, choose SECOND ORDER

in this graph

slope = k

so

slope = (1/C2-1/C1)/(t2-t1) = (1/0.349-1/0.60)/(90-0) = 0.0133184

k = slope = 0.0133184 units 1/Ms
