List of top Chemistry Questions on Law Of Chemical Equilibrium And Equilibrium Constant asked in AIIMS BSc Nursing

\([Co(H_{2}O)_{6}]^{2+}\) (Pink) \(+4Cl^{-}\rightleftharpoons[CoCl_{4}]^{2-}\) (Blue) \(+6H_{2}O\) (Endothermic reaction). If the mixture is transferred from room temperature to a freezing ice bath, what is expected to happen?

At equilibrium for the reaction N$_2$(g) + 3H$_2$(g) $\rightleftharpoons$ 2NH$_3$(g), the concentrations are [N$_2$] = 0.20 M, [H$_2$] = 0.60 M and [NH$_3$] = 0.80 M. The value of K$_c$ is:

For the reaction \[ N_2 + O_2 \rightleftharpoons 2NO \] the equilibrium concentrations are given as \[ [N_2]=0.5\,M,\qquad [O_2]=0.7\,M,\qquad [NO]=0.4\,M \] Calculate the value of \(K_c\).
