of marketing has changed. To illustrate some of the marketing
components that you have learned, identify a specific product that
could benefit from a new marketing strategy. Describe this product
and explain how you could use the information from this course to
recommend changes. Make sure to include what research strategies
you would recommend the company use to inform the new
strategies.

2 NOBr(g) Y--> 2 NO(g) + Br2(g)
How will each of the following changes affect an equilibrium mixture of the 3 gases in this reaction?
(a) NO is added to the system.
(b) The reaction mixture is heated.
(c) The volume of the reaction vessel is doubled.
(d) A catalyst is added to the reaction mixture.
(e) The total pressure of the system is increased by adding a noble gas.
(f) Br2(g) is removed from the system.

- Keq for H2O is << 1
- ΔG° is the Gibbs free energy of a reaction at equilibrium.
- All energy released from an exothermic reaction is available to do work in the cell.
- A reaction with an equilibrium constant of 2.4x10-2 proceeds forward spontaneously under standard state conditions
- Enzyme active sites undergo conformational changes in order to bind optimally to their substrates.
- A reaction with a positive ΔG will proceed in a cell as long as it has an enzyme to catalyze the reaction.

China is one of the most popular investment destinations in the world. Throughout much of the 1990s, China accounted for 50% of foreign direct investment (FDI) going into developing countries and between 1994 and 1997, China was the second largest recipient of FDI in the world, after the United States. Do you think the recent corporate tax cuts in the U.S. and the changes in tariff rates in both countries could affect FDI in China? Why? How? What about the FDI in the U.S.?
