Question 1

For the reaction: H2(g) + I2(g) 2 HI(g), Kc = 92.0
When equilibrium concentrations of HI and I2 are [HI] = 0.115 M and [I2] = 0.250 M, the equilibrium concentration of [H2] is:
◦ 5.00 × 10-3 M
◦ 5.75 × 10-4 M
◦ 1.74 × 103 M
◦ 0.135 M
◦ 9.56 M

Question 2

For the reaction: N2(g) + 2 O2(g) 2 NO2(g), Kc = 8.3 × 10-10 M-1 at 25 °C. What is the concentration of N2 gas at equilibrium when the concentration of NO2 is five times the concentration of O2 gas?
◦ 3.3 × 10-11 mol L-1
◦ 1.7 × 10-10 mol L-1
◦ 6.0 × 109 mol L-1
◦ 3.0 × 1010 mol L-1
