MCQ
For the reaction ${N_{2(g)}} + {O_{2(g)}}$ $\rightleftharpoons$ $2N{O_{(g)}}$, the value of ${K_c}$ at ${800\,^o}C$ is $0.1$. When the equilibrium concentrations of both the reactants is $0.5\, mol,$ what is the value of ${K_p}$ at the same temperature
  • A
    $0.5$
  • $0.1$
  • C
    $0.01$
  • D
    $0.025$

Answer

Correct option: B.
$0.1$
(b) ${N_{2(g)}} + {O_{2(g)}}$ $ \rightleftharpoons $ $2N{O_{(g)}}$

${K_c} = 0.1,\,{K_p} = {K_c}{(RT)^{\Delta n}}$

$\Delta n = 0,\,{K_p} = {K_c} = 0.1$
