Chemical Equilibrium question

2025 · 2 Apr · Shift 2 · Q20

JEE MainChemistryChemical EquilibriumMCQ+4 / −1
Consider the following chemical equilibrium of the gas phase reaction at a constant temperature : A(g)⇌B(g)+C(g)\mathrm{A}(\mathrm{g}) \rightleftharpoons \mathrm{B}(\mathrm{g})+\mathrm{C}(\mathrm{g})A(g)⇌B(g)+C(g) If ppp being the total pressure, KpK_pKp​ is the pressure equilibrium constant and α\alphaα is the degree of dissociation, then which of the following is true at equilibrium?
  1. A
    If KpK_pKp​ value is extremely high compared to p,αp, \alphap,α becomes much less than unity
  2. B
    When p increases α\alphaα increases
  3. C
    If p value is extremely high compared to Kp,α≈1\mathrm{K}_{\mathrm{p}}, \alpha \approx 1Kp​,α≈1
  4. D
    When ppp increases α\alphaα decreases
