Chemical Kinetics Question 173
Question: For a reaction $ 2NO(g)+Cl_2(g) $ ⇌ $ ,2NOCl(g) $ . When concentration of $ Cl_2 $ is doubled, the rate of reaction becomes two times of the original. When the concentration of NO is doubled the rate becomes four times. What is the order of the reaction [MP PMT 2000]
Options:
A) 1
B) 2
C) 3
D) 4
Show Answer
Answer:
Correct Answer: C
Solution:
$ 2N{O_{(g)}}+C{l_{2(g)}}\to 2NOC{l_{(g)}} $ Rate = $ K{{[NO]}^{2}}{{[Cl_2]}^{1}},\therefore O.R.=2+1=3 $
