Question

For the given hypothetical reactions, the equilibrium constants are as follows:
$X \rightleftharpoons Y; \, K_1 = 1.0$
$Y \rightleftharpoons Z; \, K_2 = 2.0$
$Z \rightleftharpoons W; \, K_3 = 4.0$
The equilibrium constant for the reaction
$X \rightleftharpoons W$
is:

• A. 6.0
• B. 12.0
• C. 8.0
• D. 7.0

Answer 1

Answer: (C)

8.0

Answer 2

The equilibrium constant for the net reaction $X \rightleftharpoons W$ is the product of the individual constants:
$K = K_1 \cdot K_2 \cdot K_3.$
Substitute values:
$K = 1 \cdot 2 \cdot 4 = 8.$
Final Answer:
8.0
