JEE Main 2022 — Chemical Kinetics Question with Solution

JEE Main 2022 (29 Jul Shift 1)

Question

The reaction between X and Y is first order with respect to X and zero order with respect to Y.

Experiment XmolL-1 YmolL-1 Initial ratemolL-1min-1
I 0.1 0.1 2×10-3
II L 0.2 4×10-3
III 0.4 0.4 M×10-3
IV 0.1 0.2 2×10-3

Examine the data of table and calculate ratio of numerical values of M and L.

Correct answer
40

Step-by-step explanation

Given that reaction is first order with respect to X and of zero order with respect to Y.

Means r=kXY0 Where k = rate constant.

Using data I & II

4×10-32×10-3=L0.10.20.10⇒L=0.2

Using data from  I & III

M×10-32×10-3=0.40.1⇒M=8

Not the ratio which is asked in question

ML=80.2=40
