A vessel at 1000 K contains

\mathrm{C}{\mathrm{O}_2}

with a pressure of 0.5 atm. Some of the

\mathrm{C}{\mathrm{O}_2}

is converted into

\mathrm{CO}

on the addition of graphite. If the total pressure at equilibrium is 0.8 atm, the value of

{K_p}

View answer and explanation

Correct option: A

1.8 atm

Option A (1.8 atm) is correct because the equilibrium constant is calculated based on the partial pressures of the reactants and products at equilibrium.
