(B) The equilibrium constant $K$ is defined as $K = \frac{[Products]}{[Reactants]}$.$1$. If $K$ is very small $(K $2$. If $K$ is very large $(K > 10^3)$,the reaction mixture contains mostly products.$3$. If $K$ is in the intermediate range $(10^{-3} Comparing the given values:$(1)$ $K = 0.1$ (Intermediate)$(2)$ $K = 0.02$ (Intermediate)$(3)$ $K = 0.0003$ ($3 	imes 10^{-4}$,very small,mostly reactants)$(4)$ $K = 0.002$ ($2 	imes 10^{-3}$,intermediate/small)To have high concentrations of reactants,we look for the smallest $K$ (Reaction $3$). To have high concentrations of products,we look for the largest $K$ (Reaction $1$). Thus,the pair is $(3, 1)$.
