Answer:ANSWER

Here rate law is given as:-

rate=k[NO]  

2

[O  

2

​  

]........(1)

[NO](concentration of NO) can be written as  

V

n

​  

 

where n=number of moles and V=volume

From (1)

rate=K[  

V

n

​  

]  

2

[  

V

n

​  

]......(2)

Now,

Volume is related to 1/3  

r

d

From V to  

3

V

​  

 

put new volume in (2)

New rate will be

r  

=K[  

V

3n

​  

]  

2

[  

V

3n

​  

]=K(3)  

2

[  

V

n

​  

]  

2

(2)[  

V

n

​  

]=27K[  

V

3n

​  

]  

2

[  

V

3n

​  

]

so,

r

r  

 

​  

=  

K[  

V

n

​  

]  

2

[  

V

n

​  

]

27K[  

V

3n

​  

]  

2

[  

V

3n

​  

]

​  

=27

​  

 

Rate of reaction changes by 27 times.
