Question 1

At 500.0 K, one mole of gaseous ONCl is placed in a one-liter container. At equilibrium it is 4.3% dissociated according to the equation shown here: 2ONCl

2NO + Cl₂. Determine the equilibrium constant.

◦ 4.3 × 10^–5

◦ 1.0 × 10^–3

◦ 4.5 × 10^–2

◦ 9.6 × 10^–1

◦ 2.3 × 10⁴

Question 2

At a certain temperature K for the reaction 2NO₂

N₂O₄ is 7.5 liters/mole. If 2.0 moles of NO₂ are placed in a 2.0-liter container and permitted to react at this temperature, calculate the concentration of N₂O₄ at equilibrium.

◦ 0.39 moles/liter
◦ 0.65 moles/liter
◦ 0.82 moles/liter
◦ 7.5 moles/liter
◦ None of these are correct.
