If two reactions sum to an overall reaction, and the equilibrium constants for the two reactions are K1K1 and K2K2, what is the

inessss [21]

Answer: The equilibrium constant for the overall reaction is $K_1\times K_2$

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios.

a) $A\rightarrow B+C$

$K_1=\frac{[B]\times [C]}{[A]}$

b) $B+C\rightarrow D$

$K_2=\frac{[D]}{[B]\times [C]}$

For overall reaction on adding a and b we get c

c) $A\rightarrow D$

$K_3=\frac{[D]}{[A]}$

$K_3=K_1\times K_2=\frac{[B]\times [C]}{[A]}\times \frac{[D]}{[B]\times [C]}$

$K_3=K_1\times K_2=\frac{[D]}{[A]}$

The equilibrium constant for the overall reaction is $K_1\times K_2$
