Question 1

At 340 K, K_p = 69 for the reaction H₂(g) + I₂(g) 2HI(g). 50.0 g of HI is injected into an evacuated 5.00-L rigid cylinder at 340 K. What is the total pressure inside the cylinder when the system comes to equilibrium?
◦ 2.60 atm
◦ 1.76 atm
◦ 0.424 atm
◦ 2.18 atm
◦ 10.9 atm

Question 2

At 35ºC, the equilibrium constant for the reaction 2NOCl(g)

2NO(g) + Cl₂(g) is K_c = 1.6 × 10^–5. An equilibrium mixture was found to have the following concentrations of Cl₂ and NOCl: [Cl₂] = 1.2 × 10^–2M; [NOCl] = 2.8 × 10^–1M. Calculate the concentration of NO(g) at equilibrium.
◦ 1.0 × 10^–4 M
◦ 1.0 × 10^–2 M
◦ 2.8 × 10^–1 M
◦ 2.4 × 10^–2 M
◦ 1.6 × 10^–3 M
