Question

please provide a detailed solution

Time (days) Concentration of drug Y (ng/mL) 400 350 w nr 300 250 200 150 4 1. What is the order of this reaction?

Answer 1

This is a Zero order reaction.

Time,(days) Concentration of drug = [drug] 400 350 300 250 200 In generally if the concentration difference is constant in the consecutive time gaps, that is Zero order. In this reaction [druglo - [drug]ı = 400 - (350) = 50 [drug]ı - [drug]2= 350 - 300 = 50 [drug l2 - [drug]3 = 300 - 250 = 50 [drug]3 - [drug)4 = 250 - 200= 50 [drug]4 - [drug]5 = 200-150 = 50 The difference is same, so this is a Zero order reaction.

In generally if the ln[drug] values difference is constant in the consecutive time gaps, that is first order.

In generally if the 1/[drug] values difference is constant in the consecutive time gaps, that is 2^nd order.
