1.The degree of dissociation of PCl5_55 (α\alphaα) obeying the equilibrium PCl5⇌PCl3+Cl2\mathrm{PCl_5 \rightleftharpoons PCl_3 + Cl_2}PCl5⇌PCl3+Cl2 is related to the equilibrium pressure by:a.α∝1/P4\alpha \propto 1/P^4α∝1/P4b.α∝1/P\alpha \propto 1/\sqrt{P}α∝1/Pc.α∝1/P2\alpha \propto 1/P^2α∝1/P2d.α∝P\alpha \propto Pα∝PLogin to continueOnly logged in users canattempt or see the solution.
