1 of 1

Application +4 | -1

1 mole of

\mathrm{NO}_2

and 2 moles of

\mathrm{CO}

are enclosed in a one litre vessel to attain the following equilibrium

\mathrm{NO}_2+\mathrm{CO} \leftrightharpoons \mathrm{NO}+\mathrm{CO}_2

. It was estimated that at the equilibrium,

25 \%

of initial amount of

\mathrm{CO}

is consumed. The equilibrium constant

\mathrm{K}_{\mathrm{p}}

View answer and explanation

Correct option: D

45717

Option A (

8.5

) is correct because it is calculated by determining the moles of each species at equilibrium based on the percentage of

\mathrm{S}{\mathrm{O}_2}

used up.
