Chemical Kinetics Question 236
Question: For the reaction $ N_2(g)+3H_2(g)\to 2NH_3(g) $ under certain conditions of temperature and partial pressure of the reactants, the rate of formation of $ NH_3 $ is $ 0.001,kg,{h^{-1}} $ . The rate of conversion of $ H_2 $ under the same conditions is [IIT 1994]
Options:
A) $ 1.82,\times {10^{-4}},kg/hr $
B) $ 0.0015,kg/hr $
C) $ 1.52\times 10^{4}kg/hr $
D) $ 1.82\times {10^{-14}}kg/hr $
Show Answer
Answer:
Correct Answer: B
Solution:
$ \frac{-dN_2}{dt}=\frac{-1}{3}\frac{dH_2}{dt}=\frac{1}{2}\frac{dNH_3}{dt} $
$ \frac{dH_2}{dt}=\frac{3}{2}\times 0.001=0.0015kg,h{r^{-1}}. $
