Homogeneous Equilibrium

At $120 0^{\circ} C$ , the following equilibrium is established between chlorine atoms and molecule:
$C l_{2} (g) ⇌ 2 C l (g)$
The composition of the equilibrium mixture may be determined by measuring the rate of effusion of the mixture through a pin hole. It is found that at $120 0^{\circ} C$ and $1$ atm pressure the mixture effuses $1.16$ times as fast as krypton effuses under the same condition. The equilibrium constant $K_{c}$ is:

One mole of $C a C O_{3}$ is taken in one litre container which on heating decomposes according to the equation
$C a C O_{3} (s) \to C a O (s) + C O_{2} (g)$
The $K_{P}$ for the reaction is 1 atm at $2 7^{C}$ . Then the maximum amount of CaO that can be produced in this reaction is

The equilibrium constant for the disproportionation of $H g C l_{2}$ into $H g C l^{+}$ and $H g C l_{3}^{-}$ is ...............
Given, $H g C l^{+} + C l^{-} ⇌ H g C l_{2}; K_{1} = 3 \times 10^{6}$
$H g C l_{2} + C l^{-} ⇌ H g C l_{3}^{-}; K_{2} = 9.0$

A sample of $H I (g)$ is placed in a flask at a pressure of $0.2 a t m$ . At equilibrium the partial pressure of $H I (g)$ is $0.04 a t m$ . What is $K_{p}$ for the given equilibrium?

$2 H I (g) ⇌ H_{2} (g) + I_{2} (g)$

The total pressure at which A $()$ is $50 %$ dissociated according to the equation A $() \Leftrightarrow B () + C ()$ is numerically equal to...........times of Kp.

The plot shows the variation of $- ln K_{p}$ versus temperature for the two reactions.
$M (s) + \frac{1}{2} O_{2} (g) \to M O (s)$ and
$C (s) + \frac{1}{2} O_{2} (g) \to C O (s)$
Identify the correct statement:

The equilibrium constant K for a reaction is related to the equilibrium constant of the corresponding reaction, whose equation is obtained by multiplying or dividing the equation for the original reaction by a small integer.

For the following gaseous reaction $H_{2} + I_{2} ⇌ 2 H I$ , the equilibrium constant:

For the following homogeneous reaction, the equilibrium constant K has units as:

$4 N H_{3} + 5 O_{2} ⇌ 4 N O + 6 H_{2} O$

The rate of disappearance of $A$ in the reaction at equilibrium $A ⇌ B$ is given by :
$- \frac{d [ A ]}{d t} = 2 \times 10^{- 2} [A] - 4 \times 10^{- 3} [B]$ at $300 K$ .

The equilibrium constant $K_{c}$ is :
