List of top Chemistry Questions on Equilibrium Constant asked in MET

The chemical reaction of a gas phase is given below. \[ 2A(g) + B(g) \rightleftharpoons C(g) + D(g) \] Which one of the following changes will affect the value of \(K_c\)?

\(9.2\mathrm{g}\ \mathrm{N}_2\mathrm{O}_4\) is heated in 1L vessel till equilibrium state is established.
\(\mathrm{N}_2\mathrm{O}_4(\mathrm{g})\rightleftharpoons 2\mathrm{NO}_2(\mathrm{g})\)
In equilibrium state, \(50%\ \mathrm{N}_2\mathrm{O}_4\) was dissociated, equilibrium constant will be (molecular wt. of \(\mathrm{N}_2\mathrm{O}_4 = 92\))

Equivalent amounts of \(\mathrm{H}_2\) and \(\mathrm{I}_2\) are heated in a closed vessel till equilibrium is obtained. If \(80%\) of the hydrogen can be converted to \(\mathrm{HI}\), the \(K_C\) at this temperature is

$ Ca{{(HC{{O}_{3}})}_{2}}(s) $ decomposes as $ Ca{{(HC{{O}_{3}})}_{2}}(s)\xrightarrow[{}]{{}}CaC{{O}_{3}}(s)+{{H}_{2}}O(g) $ $ +C{{O}_{2}}(g) $ Total pressure at equilibrium is found to be 0.12 bar. Thus, $ {{K}_{p}} $ is
