Problem

Two elementary equilibria are given below at the same temperature. (1) X

\rightleftharpoons

K_1 = 2.0\times10^{3}

(2) Y

\rightleftharpoons

K_2 = 5.0\times10^{-2}

Which of the following best represents the magnitude of the equilibrium constant

K_{\text{overall}}

for the reaction X

\rightleftharpoons

Z obtained by adding reactions (1) and (2)? a)

K_{\text{overall}} \approx 2.0\times10^{3}

K_{\text{overall}} \approx 2.5\times10^{1}

K_{\text{overall}} \approx 1.0\times10^{2}

K_{\text{overall}} \approx 1.0\times10^{6}
