Equilibrium Question 473
Question: For the gaseous phase reaction 2NO ⇌ $ N_2+O_2\Delta H{}^\circ =+\ 43.5kcal,mo{l^{-1}} $ Which statement is correct [MH CET 1999]
Options:
A) K varies with addition of NO
B) K decrease as temperature decreases
C) K Increases as temperature decreases
D) K is independent of temperature
Show Answer
Answer:
Correct Answer: B
Solution:
2.303 log $ \frac{K_2}{K_1}=\frac{\Delta H}{R}\frac{[T_2-T_1]}{T_1\times T_2} $
$ \Delta H= $ +ve for the reaction
