Kp for the decomposition of N2O4 is 0.143 at 25°C. If the initial pressure of N2O4 in a

1.00L flask at

25°C is 0.0500atm, what will be the partial pressures of N2O4 and NO2 and the total

pressure at

equilibrium?

N2O4(g) ⇄ 2NO2(g)

Given at 25°C:

2Cl2(g) + 2H2O(g) ⇄ 4HCl(g) + O2(g) Kp = 3.2x10-14

Write the equilibrium constant expressions for Kc and Kp and calculate their values for

the reaction

writing in the following forms:

a. 4HCl(g) + O2(g) ⇄ 2Cl2(g) + 2H2O(g)

b. 2HCl(g) + ½O2(g) ⇄ Cl2(g) + H2O(g)

c. Cl2(g) + H2O(g) ⇄ 2HCl(g) + ½O2(g)

d. 4Cl2(g) + 4H2O(g) ⇄ 8HCl(g) + 2O2(g)

e. ½Cl2(g) + ½H2O(g) ⇄ HCl(g) + ¼O2(g)

Bromine chloride, BrCl, is a reddish covalent gas with properties similar to those of

Cl2, may eventually replace Cl2 as a water disinfectant. One mole of chlorine and one mole

of bromine are enclosed in a 5.0L flask and allowed to reach equilibrium at a certain

temperature.

Cl2(g) + Br2(g) ⇄ 2BrCl(g) Kc = 4.7x10-2

We place 0.500mole CO, 0.500mole H2O, 0.500mole CO2, and 0.500mol H2 in a 1.00L

container under the conditions in problem #8. What will be the equilibrium concentrations

of all species present?

gwi nam is working on a fluid which flows at 10lb/min and operates at steady flow process in his laboratory.The fluid has an initial pressure of 200 psia dropped to 20 psia.Its speed increases from 200 ft/s to a final velocity of 1000ft/s.The internal energy decreases 25 BTU/lbm and the specific volumes increases from 18 cubic ft/lb.Assuming that no heat is transferred.Determine the work done in BTU/min.
