Soru 1
A reaction occurs via two steps at equilibrium:
Step 1: $X \rightleftharpoons Y$ with $K_{c1} = 4.0$
Step 2: $Y \rightleftharpoons Z$ with $K_{c2} = 0.5$
Calculate the equilibrium constant $K_c$ for the net reaction $X \rightleftharpoons Z$.

Çözüm
Since the net reaction is the sum of the two equilibrium steps, $K_c = K_{c1} \times K_{c2} = 4.0 \times 0.5 = 2.0$.
