Question

A gas X reacts reversibly and independently to form two different gases, Y and Z:
X(g) ⇌ Y(g) KY
X(g) ⇌ Z(g) KZ
At a certain temperature, the time evolution of the pressures of the three gases are shown. What is the equilibrium constant KY at this temperature?

A.

3.0

B.

8.0

✓ Correct
C.

9.3

D.

It cannot be determined because the system has not yet reached equilibrium.
