Equilibrium Question 594
Question: The formation of $ SO_3 $ takes place according to the following reaction, $ 2SO_2+O_2 $ ⇌ $ 2SO_3 $ ; $ \Delta H=-45.2\ kcal $ The formation of $ SO_3 $ is favoured by [UPSEAT 2004]
Options:
A) Increasing in temperature
B) Removal of oxygen
C) Increase of volume
D) Increasing of pressure
Show Answer
Answer:
Correct Answer: D
Solution:
In this reaction $ \Delta H $ is negative so reaction move forward by decrease in temperature while value of $ \Delta n=2-3=-1 $ i.e., negative so the reaction move forward by increase in pressure.
