Document Summary

At a particular temperature, the equilibrium constant for this system is k = 6. 67. A 4. 0 l flask is filled with 0. 33 mol so2, 0. 33 mol o2, and 0. 33 mol so3, and allowed to reach equilibrium. Ans: a: an aqueous mixture of hydrocyanic acid and ammonia has initial concentrations of 0. 100 m hcn(aq) and 0. 140 m nh3(aq). B: the equilibrium constant, k, for the following reaction is 8. 12 at a particular temperature. If 15. 0 g sno2 and 0. 855 mol h2 are allowed to equilibrate in a 5. 0 l flask at the temperature described above, what is the concentration of h2: 0. 044, 0. 076, 0. 11, 0. 16. Ans: a: at a high temperature, equal concentrations of 0. 200 mol/l of h2(g) and i2(g) are initially present in a flask. The h2 and i2 react according to the following balanced equation: When equilibrium is reached, the concentration of h2(g) has decreased to 0. 046 mol/l.
