X, Y and Z are all gases that behave ideally and react according to the equation shown. X(g) + 2Y(g) → 2Z(g) When 3.0 mol of X and 3.0 mol of Y are placed inside a container with a volume of 1.0 dm³, they react to form the maximum amount of Z. The final temperature of the reaction vessel is 120 °C. What is the final pressure inside the reaction vessel?

B9.80 × 10⁶ Pa
C1.47 × 10⁷ Pa
D1.96 × 10⁷ Pa
✓ Correct answer
C: 1.47 × 10⁷ Pa
