For the reaction

C(s) + C{O_2}(g)2\,\,CO(g)

the partial pressure of

C{O_2}

and are 2.0 and 4.0 atm resp, at equilibrium. The

{K_p}

for the reaction is

View answer and explanation

Correct option: C

3.0

Option D (32.0) is correct because Kp is calculated as the ratio of the partial pressure of products to reactants, each raised to the power of their stoichiometric coefficients.
