Chapter 7.5, Problem 46E

Reaction Rates In a chemical reaction, the reaction rate R is a function of the concentraton of the product of the reaction. For a certain second-order reaction between two substances, we have the formula R=0.01x2x+22. Here x is measured in moles per cubic meter and R is measured in moles per cubic meter per second. a. Make a graph of R versus x. Include concentrations up to 100 moles per cubic meter. b. Use functional notation to express the reaction rate when the concentration is 15 moles per cubic meter, and then calculate hat value. c. The reaction is said to be in equilibrium when the reaction rate is 0. At what two concentratoins is the reaction in equilibrium?

A rectangular package sent by a delivery service can have a maximum combined length and girth (perimeter of a cross section) of 120 inches (see figure). 47°F Sunny (a) Determine which of the following functions gives the volume of the package. (Assume the volume is measured in cubic inches.) O V(x) = 30x²(4- x) 4 O V(x) = 4x² (30 - x) O V(x)= 30x2(120 - x) O v(x) = 120x²(4 - x) O V(x) = 4x²(120 - x) (b) Use a graphing utility to graph the function.
