The rate of a chemical reaction varies, depending on the initial amount of a certain compound. In general, the reaction rate, v, can be expressed by the following formula, where k is a positive constant, and a is the initial amount of the compound.
v(x)=kx(a-x)
the positive constant, k, for one such reaction, is 0.9, and the initial amount of the compound, a, is 14. For what value of x is the rate a maximum?
