$K_p$ does not change but $\alpha$ changes.

(D) $1$. The equilibrium constant $K_p$ depends only on temperature. Since the temperature is constant,$K_p$ remains unchanged.$2$. For the reaction $N_2O_4(g) \rightleftharpoons 2NO_2(g)$,the equilibrium constant $K_p$ in terms of degree of dissociation $\alpha$ and total pressure $P$ is given by $K_p = \frac{4\alpha^2 P}{1 - \alpha^2}$.$3$. When the volume of the vessel is halved,the total pressure $P$ increases. To keep $K_p$ constant at a fixed temperature,the degree of dissociation $\alpha$ must decrease to compensate for the increase in pressure.$4$. Therefore,$K_p$ remains constant,but $\alpha$ changes.

Solid carbon, $CaO$ and $CaCO_3$ are mixed and allowed to attain equilibrium at $T \text{ K}$. $CaCO_3(s) \rightleftharpoons CaO(s) + CO_2(g)$ $K_{p1} = 0.08 \text{ atm}$. $C(s) + CO_2(g) \rightleftharpoons 2CO(g)$ $K_{p2} = 2 \text{ atm}$. The partial pressure of $CO$ is . . . . . . $\times 10^{-1} \text{ atm}$.
