Chemical Kinetics Question 85
Question: The reaction $ N_2O_5,(in,CCl_4,solution)\to 2NO_2(solution)+\frac{1}{2}O_2(g) $ is of first order in $ N_2O_5 $ with rate constant $ 6.2\times {10^{-1}}{s^{-1}}. $ What is the value of rate of reaction when $ [N_2O_5]=1.25,mole,{l^{-1}} $ [AFMC 1998]
Options:
A) $ 7.75\times {10^{-1}}mole,{l^{-1}}{s^{-1}} $
B) $ 6.35\times {10^{-3}}mole,{l^{-1}}{s^{-1}} $
C) $ 5.15\times {10^{-5}}mole,{l^{-1}}{s^{-1}} $
D) $ 3.85\times {10^{-1}}mole,{l^{-1}},{s^{-1}} $
Show Answer
Answer:
Correct Answer: A
Solution:
Rate $ =K(N_2O_5)=6.2\times {10^{-1}}\times 1.25 $
$ =7.75\times {10^{-1}}mol{l^{-1}}{s^{-1}} $
