0CORRECT-INCORRECT STATEMENT
\( \mathbf{S}_{1} \) : When a liquid and its vapour are at equilibrium and the pressure is suddenly decreased, cooling occurs.
\( S_{2} \) : If equilibrium constant for the reaction, \( \mathrm{A}_{2}+\mathrm{B}_{2} \rightleftharpoons 2 \mathrm{AB} \), is \( \mathrm{K} \), then for the backward reaction
\( \mathrm{AB} \rightleftharpoons \frac{1}{2} \mathrm{~A}_{2}+\frac{1}{2} \mathrm{~B}_{2} \), the equilibrium constant is \( \frac{1}{\mathrm{~K}} \) ?
\( \mathrm{S}_{3} \) : Catalyst makes a reaction more exothermic.
