Chemical Equilibrium question

2023 · 1 Feb · Shift 2 · Q9

JEE MainChemistryChemical EquilibriumMultiple correct+4 / −1
The effect of addition of helium gas to the following reaction in equilibrium state, is : PCl5(g)⇌PCl3(g)+Cl2(g)\mathrm{PCl}_{5}(\mathrm{g}) \rightleftharpoons \mathrm{PCl}_{3}(\mathrm{g})+\mathrm{Cl}_{2}(\mathrm{g})PCl5​(g)⇌PCl3​(g)+Cl2​(g)
  1. A
    the equilibrium will shift in the forward direction and more of Cl2\mathrm{Cl}_{2}Cl2​ and PCl3\mathrm{PCl}_{3}PCl3​ gases will be produced.
  2. B
    addition of helium will not affect the equilibrium.
  3. C
    helium will deactivate PCl5\mathrm{PCl}_{5}PCl5​ and reaction will stop.
  4. D
    the equilibrium will go backward due to suppression of dissociation of PCl5\mathrm{PCl}_{5}PCl5​.
