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

Did you know?

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
