Equilibrium Quiz-1

For the reaction : $CO(g) + \frac12O_2(g)\rightleftharpoons CO_2(g) ; K_p / K_c$ is

What is the equilibrium expression for the following reaction?$P_{4(s)} + 5O_{2(g)}\rightleftharpoons P_4O_{10(s)}$

A mixture of $N_2$ and $H_2$ in the molar ratio 1:3 attains equilibrium when 50% of the mixture has reacted. If P is the total pressure of the mixture then partial pressure of $NH_3$ formed is

A and B are gaseous substances which react reversibly to give two gaseous substances C and D, accompanied by the liberation of heat. When the reaction reaches equilibrium, it is observed that $K_p = K_c$. The equilibrium cannot be disturbed by

The value of equilibrium constant for an endothermic reaction

A reaction reaches a state of chemical equilibrium only when

According to Le Chatelier’s principle, adding heat to a solid and liquid in equilibrium will cause the

Vapour density of $PCl_5$ is 104.16 but when heated at $230^\circ C$ its vapour density is reduced to 62. The degree of dissociation of $PCl_5$ at this temperature will be

The vapour density of completely dissociated $NH_4Cl$ would be :

If the reaction $N_2O_4\rightleftharpoons 2NO_2$, is started with one mole of $N_2O_4$ and $\alpha$ is degree of dissociation of $N_2O_4$ then the number of moles at equilibrium will be :
