NEETChemistryChemical EquilibriumMCQ+4 / −1

In which of the following equilibria, Kp\mathrm{K}_pKp​ and Kc\mathrm{K}_{\mathrm{c}}Kc​ are NOT equal?

  1. A
    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)​
  2. B
    H2( g)+I2( g)⇌2HI(g)\mathrm{H}_{2(\mathrm{~g})}+\mathrm{I}_{2(\mathrm{~g})} \rightleftharpoons 2 \mathrm{HI}_{(\mathrm{g})}H2( g)​+I2( g)​⇌2HI(g)​
  3. C
    CO(g)+H2O(g)⇌CO2( g)+H2( g)\mathrm{CO}_{(\mathrm{g})}+\mathrm{H}_2 \mathrm{O}_{(\mathrm{g})} \rightleftharpoons \mathrm{CO}_{2(\mathrm{~g})}+\mathrm{H}_{2(\mathrm{~g})}CO(g)​+H2​O(g)​⇌CO2( g)​+H2( g)​
  4. D
    2BrCl(g)⇌Br2( g)+Cl2( g)2 \mathrm{BrCl}_{(\mathrm{g})} \rightleftharpoons \mathrm{Br}_{2(\mathrm{~g})}+\mathrm{Cl}_{2(\mathrm{~g})}2BrCl(g)​⇌Br2( g)​+Cl2( g)​
