In which of the following equations can Le-chartelier’s principle be applied?
- H2(g)+S(g) → H2(g)
- 2H2S(g) + O2 (g) → 2H2O(l) + 2SO2(g)
-
N2(g) +3H2(g)
⇌ 2NH3(g)
- NaOH(aq) +CO2(g) → Na2CO3(aq) + H2O(l)
- S(s) + 02(g) → SO2(g)
The correct answer is: C
Explanation
According to Le Chatelier's Principle, this will be favored if you lower the temperature. The system will respond by moving the position of equilibrium to counteract this - in other words by producing more heat. To get as much ammonia as possible in the equilibrium mixture, you need as low a temperature as possible
