Question 1

2.50 mol NOCl was placed in a 2.50 L reaction vessel at 400ºC. After equilibrium was established, it was found that 28% of the NOCl had dissociated according to the equation
2NOCl(g)

2NO(g) + Cl₂(g).
Calculate the equilibrium constant, K_c, for the reaction.

Question 2

25.0 g of HI(g) is injected into a 4.00 L reaction vessel that contains 20.0 g of I₂(g). When the system comes to equilibrium at 400ºC, what will be the total pressure inside the reaction vessel?
2HI(g)

H₂(g) + I₂(g), K_c = 0.0156 at 400ºC
