Tampa Electric Company (TECO) is planning a major upgrade in its computerized demand management system. In order to accommodate this upgrade, a building will be constructed on land already owned by the company. The building is estimated to cost $1.8M and will be opened in August of this year. The computer equipment for the building will cost$2.75M, and all office equipment will cost $225,000. Annual expenses for operating this facility (labor, materials, insur- ance, energy, etc.) are expected to be$325,000 for the rest of this year. Use of the new demand management system is expected to decrease fuel and other costs for the company by $1.8M this year. If the company expects to earn 9% on its investments, is in the 35% tax bracket, and uses a 20-year planning horizon, determine the estimated after-tax cash flow from this project for this year.

Both the forward reaction and the reverse reaction in the following equilibrium are believed to be elementary steps:

$$\mathrm { CO } ( g ) + \mathrm { Cl } _ { 2 } ( g ) \rightleftharpoons \operatorname { COCl } ( g ) + \mathrm { Cl } ( g )$$

At

$$25 ^ { \circ } \mathrm { C }$$

the rate constants for the forward and reverse reactions are

$$1.4 \times 10 ^ { - 28 } M ^ { - 1 } \mathrm { s } ^ { - 1 }$$

and

$$9.3 \times 10 ^ { 10 } \mathrm { M } ^ { - 1 } \mathrm { s } ^ { - 1 }$$

respectively. What is the value for the equilibrium constant at

$$25 ^ { \circ } \mathrm { C } ?$$
