Reaction rates: In a chemical reaction, the reaction rate R is a function of the concentration x of the product of the reaction. For a certain secondorder reaction between two substances, we have the formula

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 that value.

c. The reaction is said to be in equilibrium when the reaction rate is 0.At what two concentrations is the reaction in equilibrium?
