Be sure to answer all parts. The water-gas shift reaction plays a central role in the chemical methods for obtaining cleaner fuels from coal: CO(g) + H2O(g) ⇌ CO2(g) + H2(g) A study was made in which equilibrium was reached with [CO] = [H2O] = [H2] = 0.100 M and [CO2] = 0.400 M. After 1.40 mol of H2 is added to the 2.00−L container and equilibrium is reestablished, what are the new concentrations of all the components?

2. Use the following data (measured at 1200 K) to estimate the value of Kp at 1200 K for the reaction:

2H2(g) + O2(g) ↔ 2H2O(g)
Data:

C(graphite) + CO2(g) ↔ 2CO(g) Kc = 0.64
CO2(g) + H2(g) ↔ CO(g) + H2O(g) Kc = 1.4
C(graphite) + 1/2 O2(g) ↔ CO(g) Kc = 1.0 x 108

a) Define the following terms: (i) ferroelectric (ii) piezoelectric

b)Draw perspective and plan views of the unit cell of cubic barium titanate. Label the fractional co-ordinates of the non-equivalent ions and state the co-ordination number of the ions. [6 marks] (ii) Describe, with the aid of appropriate diagrams, the various structural changes which occur as a barium titanate crystal cools from 200°C to -100°C. Specify the temperatures of the relevant phase transitions.

1. Predict whether each of the following equilibria will shift toward products or reactants with a temperature increase:

a. CH4(g) + H2O(g) === CO(g) + 3H2( g) Delta H = +206kJ

b. CO(g) + H2O(g) CO2(g) + H2(g) Delta H = -41 kJ

c. 2SO2(g) + O2(g) = 2SO3(g) Delta H = -198 kJ

d. N2O4 (g) ===== 2NO2 (g) Delta H = + 57kJ

The Newton Co. is a new firm in a rapidly growing industry. The company is planning on increasing its annual dividend by 15% a year for the next four years (Year 1, Year 2, Year 3, and Year 4) and then increase at the constant growth rate of 5% per year indefinitely. The company just paid its annual dividend in the amount of $1.50 per share. What is the current value of Newton Co.’s stock if the required rate of return is 8%?

1. In competitive, common-product environment, a seller would most likely use: A. time-and-material pricing B. variable costing C. target costing D. Cost-plus pricing

2. Mystique Co. provides the following information for the new product if recently introduced: Total unit cost $30 Desired ROI per unit $10 Target selling price $40 What would be Mystique Co.’s percentage markup on cost?

Iron (III) oxide reacts with carbon monoxide to produce iron and carbon dioxide:

Fe2O3 (s) + 3CO(g)  2Fe (s) + 3 CO2 (g)

54.4 g of Fe2O3and 24.7 g of CO react to produce iron.

Molar mass of Fe2O3 = 159.69 g/mol. Molar mass of CO = 28.01 g/mol.

Determine the (a) limiting reactant, (b) theoretical yield, and (c) percent yield for the reaction if 29.1 g of iron are produced.

Consider the following reaction:

CO(g)+2H2(g)⇌CH3OH(g)CO(g)+2H2(g)⇌CH3OH(g)

The reaction between COCO and H2H2 is carried out at a specific temperature with initial concentrations of COCO = 0.26  M M and H2H2 = 0.49  M M. At equilibrium, the concentration of CH3OHCH3OH is 0.16  M M.
