QJEEM20Chc0ba: JEE Main 2020 Chemistry - Class 12 JEEM20Chc0ba Solution: Consider the following reactions A P 1 ; B P 2 ; C P 3 ; D P 4…

Consider the following reactions

A →\to P1 ; B →\to P2 ; C →\to P3 ; D →\to P4,

The order of the above reactions are a, b, c, and d, respectively. The following graph is obtained when log[rate] vs. log[conc.] are plotted JEE Main 2020 (Online) 6th September Morning Slot Chemistry - Chemical Kinetics and Nuclear Chemistry Question 108 English
Among the following, the correct sequence for the order of the reactions is :

Multiple Choice Options

  • A d > b > a > c
  • B d > a > b > c
  • C a > b > c > d
  • D c > a > b > d

Step-by-Step Verified Solution

Rate = k[A]n

log[Rate] = log k + n log [A]

slope = n [n is order of the reaction]

So, Which one has higher slope will have higher order.

∴\therefore Correct sequence for the order of the reaction is
d > b > a > c
