The decomposition of hydrogen peroxide in dilute sodium hydroxide at 20°C 2 H2O2(aq) 2 H2O(l) + O2(g) has the following relationship between rate and concentration, where the bracket around the formula indicates concentration and k is a constant called the rate constant. Rate = k[H2O2] If the rate of the reaction is 3.12×10-5 M min-1 when [H2O2] = 1.87×10-2 M, what is the value of k?

The Specialty Chemical Company operates a crude oil refinery located in New Iberia, Louisiana. The company refines crude oil and sells the by-products to companies that make plastic bottles and jugs. The firm is currently planning for its refining needs for one year hence. Specifically, the firm's analysts estimate that Specialty will need to purchase 1 million barrels of crude oil at the end of the current year to provide the feed stock for its refining needs for the coming year. The 1 million barrels of crude will be converted into by-products at an average cost of $4040 per barrel that Specialty expects to sell for $170170 million, or $170170 per barrel of crude used. The current spot price of oil is $125125 per barrel and Specialty has been offered a forward contract by its investment banker to purchase the needed oil for a delivery price in one year of $130130 per barrel. a. Ignoring taxes, what will Specialty's profits be if oil prices in one year are as low as $110110 or as high as $150150, assuming that the firm does not enter into the forward contract? b. If the firm were to enter into the forward contract, demonstrate how this would effectively lock in the firm's cost of fuel today, thus hedging the risk of fluctuating crude oil prices on the firm's profits for the next year.

Figure 17-1 Production Function Real GDP = T (L, K), such that Real GDP = T(L + K) Assume that the technology coefficient is equal to 0.40. Refer to Figure 17-1. If this production function is graphed with Real GDP on the vertical axis and labor on the horizontal axis, and the technology coefficient rises from 0.40 to 0.50, it would cause a a. movement up along the same production function to a higher level of Real GDP. b. shift upward in the production function to a higher level of Real GDP. c. shift downward in the production function to a lower level of Real GDP. d. movement down along the same production function to a lower level of Real GDP.
