List of top Chemistry Questions on Equilibrium asked in AP EAPCET

Given below are two statements:
Statement I: Physical equilibrium takes place only in closed systems at a given temperature
Statement II: For an equilibrium reaction, $\Delta_r G$ is zero

Consider the following reaction: $A(g) + B(g) \rightleftharpoons C(g) + D(g)$. Which one of the following is zero for this reaction at 298 K?

Consider the equilibrium reactions:

The equilibrium constant, $K_c$, for the overall dissociation \[ H_3PO_4 \rightleftharpoons 3H^+ + PO_4^{3-} \] is:

For the reaction $CaCO_3(s) \rightleftharpoons CaO(s) + CO_2(g)$, complete conversion of $CaCO_3$ can be achieved by:

Statement (A): Addition of an inert gas at equilibrium at constant volume does not affect equilibrium.
Statement (B): Addition of a catalyst does not affect the position of equilibrium.
Choose the correct option.

The \(K_a\) values of A, B and C are \(1.8\times 10^{-4}\), \(5\times 10^{-10}\) and \(3\times 10^{-8}\) respectively. The correct order of their acidic strength is

For a reaction \[ A(g)+\frac{1}{2}B(g)\rightleftharpoons C(g)+\text{heat} \] favorable conditions for the reaction to occur in the forward direction are
