NEET2018ChemistryChemical EquilibriumActual
Which one of the following conditions will favor the maximum formation of the product in the reaction? A 2   g + B 2   g ⇌ X 2   g    Δ r H = - X   kJ
Options
- AHigh temperature and high pressure.
- BLow temperature and low pressure.
- CLow temperature and high pressure.
- DHigh temperature and low pressure.
Correct answer
C. Low temperature and high pressure.
Step-by-step solution
log k 2 k 1 = Δ H 2 .303 K ( 1 T 1 − 1 T 2 ) ∴ Δ H = − ve and for the maximum formation of the product k 2 > k 1 hence, T 1 > T 2 mean temperature should decrease Δ n g = − ve k p ∝ 1 p on increasing p reaction goes in forward direction.
