APCHEM-OIYD4M

For the reaction:

$$2X(g) ⇄ 2Y(g) + Z(g)$$

...the $K_p = 1.79$ at $368 \ \text{K}$.

A mixture of the three gases at 368 K is placed in a rigid metal cylinder, and the initial pressures are $P_x$ = 1 atm, $P_y$ = 0.8 atm, and $P_z$ = 2 atm.

At the instant of mixing, which of the following is TRUE?

A

More product will form.

B

More reactant will form.

C

$ΔS = 0$

D

$ΔGº > 0$
