JEE Main & Advanced Sample Paper JEE Main Sample Paper-33

The following data are obtained for a reaction, \[X+Y\to \] Products.

Expt. \[[{{X}_{0}}]/mol\] \[[{{Y}_{0}}]/mol\] \[rate/mol\] \[{{L}^{-1}}{{s}^{-1}}\]

1 0.25 0.25 \[1.0\times {{10}^{-6}}\]

2 0.50 0.50 \[4.0\times {{10}^{-6}}\]

3 0.25 0.25 \[8.0\times {{10}^{-6}}\]

The overall order of the reaction is:

A) 2

B)                    4

C) 3

D)                    5

Correct Answer: D

Solution :

Rate \[=K.\,{{[X]}^{p}}\,{{[Y]}^{q}}\] From expt. 1 and 2, p = 2 and from expt. 1 and 3, q = 3. Therefore, over all order = 5.
