Expert Solution
Step 1

If we follow the data in the given table then we observe that even after tripled the concentration of B ,the reaction time doesn't change. From the data we can conclude few things:

1) While performing the experiment the concentration of A & C remain constant. Concentratie of B is tripled.

2) There is no change in reaction time. Since dramatic colour change take same time from the time of mixing in each case.

3) Even after tripling the concentration of B the reaction time doesn't change. Hence it must be Zero order with respect to B.
