For the decomposition $CaCO X_{3} (s) CaO (s) + CO X_{2} (g)$ , $Δ H > 0$ , carried out in a closed vessel with excess solids present, select the correct statements.

A $K_{p}$ increases on heating
BThe equilibrium pressure of $CO X_{2}$ increases on heating
CAdding argon at constant $T$ and $V$ increases the equilibrium pressure of $CO X_{2}$
DHeating increases the amount of $CaO$ at equilibrium

K_{p} = p_{C O_{2}}

, and for an endothermic reaction it rises with

T

(A, B). More

CaCO X_{3}

decomposes, increasing

CaO

(D). Argon at constant

V

does not change

p_{C O_{2}}

(C false).
