Answer
(a) $Kp1$
(b) $1/Kp1$
(c) $Kp1$
(d) $Kp1$
(e) $Kp1^2$
Work Step by Step
(a) Given the reaction
$$CO+\frac{1}{2}O_2\Longleftrightarrow CO_2\text{ at }3\text{ atm}$$ The equilibrium constant of the reaction at $3000\text{ K}$ in terms of $K_p$ is $Kp1$.
(b) Given the reaction
$$CO_2\Longleftrightarrow CO+\frac{1}{2}O_2\text{ at }1\text{ atm}$$ The equilibrium constant of the reaction at $3000\text{ K}$ in terms of $K_p$ is $1/Kp1$.
(c) Given the reaction
$$CO+O_2\Longleftrightarrow CO_2+\frac{1}{2}O_2\text{ at }1\text{ atm}$$ The equilibrium constant of the reaction at $3000\text{ K}$ in terms of $K_p$ is $Kp1$.
(d) Given the reaction
$$CO+2O_2+5N_2\Longleftrightarrow CO_2+1.5O_2+5N_2\text{ at }4\text{ atm}$$ The equilibrium constant of the reaction at $3000\text{ K}$ in terms of $K_p$ is $Kp1$.
(e) Given the reaction
$$2C)+O_2\Longleftrightarrow 2CO_2\text{ at }1\text{ atm}$$ The equilibrium constant of the reaction at $3000\text{ K}$ in terms of $K_p$ is $1/Kp1^2$.
