Chemistry Question from JEE Main 2025 · 23 January, Shift 2

Consider the reaction: X2Y(g)⇌X2(g)+12Y2(g)X_2Y(\text{g}) \rightleftharpoons X_2(\text{g}) + \frac{1}{2} Y_2(\text{g})

The equation representing the correct relationship between the degree of dissociation xx of X2Y(g)X_2Y(\text{g}) with its equilibrium constant KpK_p is _____. Assume xx to be very very small.

  • A

    x=2Kpp3x = \sqrt[3]{\dfrac{2K_p}{p}}

  • B

    x=2Kp2p3x = \sqrt[3]{\dfrac{2K_p^2}{p}}

  • C

    x=Kp2p3x = \sqrt[3]{\dfrac{K_p}{2p}}

  • D

    x=Kpp3x = \sqrt[3]{\dfrac{K_p}{p}}
