Answer:

$P_2=7.09atm$

Explanation:

Hello!

In this case, given the change in volume and pressure of the gas, it is possible for us to recall the Boyle's law as way to understand the inversely proportional relationship between pressure and volume:

$P_1V_1=P_2V_2$

Thus, when solving for the final pressure, P2, given the initial pressure and volume and the final volume, we obtain:

$P_2=\frac{P_1V_1}{V_2}\\\\P_2=\frac{2.27atm*2.50L}{0.80L}\\\\P_2=7.09atm$

Best regards!

CH4(g) + H2O(g) CO(g) + 3H2(g)

boyakko [2]

Presuming the arrow is between H20 and CO

On the left there are 2 gas moles.
On the right there are 4 gas moles.

The equilibrium will shift to the side with the most no. He gas moles when pressure is decreased.

Therefore the answer is A, since 4>2.
