Chemical engineering

Ethylene oxide is produced by reacting ethylene with oxygen. The feed to the reactor contains 5 moles of ethylene, 3 moles of oxygen, and 2 moles of ethylene oxide. Set up the compound balances in general and then use these to answer the questions below using the extent of reaction approach. Make sure to interpret the result for each question.

\[
2C_2H_4 + O_2 \rightarrow 2C_2H_4O \quad (1)
\]

(a) Suppose that \( n_{C_2H_4} = 5 \) mol (i.e., the amount of ethylene coming out of the reactor is 5 moles), how much reaction has occurred?

(b) Suppose \( n_{C_2H_4} = 6 \) mol, how much reaction has occurred?

(c) Suppose \( n_{C_2H_4} = 0 \) mol, how much reaction has occurred?

(d) Which component is the limiting reagent, and what is the theoretical yield?

(e) Suppose \( n_{C_2H_4} = 2 \) mol, what is the fractional conversion?
