For the reaction, 2H2S(g) + O2(g) 25(s) +
2H2O(l), which one of the following
statements is absolutely true?
The reaction is first order with respect to
O H2S and second order with respect to
02.
O The reaction is fourth order overall
.
O The rate law is: rate = k[H2S]2[02].
O
The rate law cannot be determined from
the information given.

Answer:
Explanation:ere 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

[
V
3n
]=K(3)

[
V
n

(2)[
V
n
]=27K[
V
3n
]
2
[
V
3n
]
so,
r
r
′
=
K[
V

[
V

27K[
V
3n
]
2
[

=27
Rate of reaction changes by 27 times.
