Chemical Reaction In a chemical reaction, one unit of compound Y and one unit of
Chapter 8, Problem 50(choose chapter or problem)
In a chemical reaction, one unit of compound Y and one unit of compound Z are converted into a single unit of compound X. Let \(x\) be the amount of compound X formed. The rate of formation of X is proportional to the product of the amounts of unconverted compounds Y and Z. So, \(d x / d t=k\left(y_{0}-x\right)\left(z_{0}-x\right)\), where \(y_{0}\) and \(z_{0}\) are the initial amounts of compounds Y and Z. From this equation, you obtain
\(\int \frac{1}{\left(y_{0}-x\right)\left(z_{0}-x\right)} d x=\int k d t\)
(a) Perform the two integrations and solve for \(x\) in terms of \(t\).
(b) Use the result of part (a) to find \(x\) as \(t \rightarrow \infty\) for (1) \(y_{0}<z_{0}\), (2) \(y_{0}>z_{0}\), and (3) \(y_{0}=z_{0}\).
