takes place in a batch reactor. When the reaction mixture comes to equilibrium, the mole fractions of the four reactive species are related by the reaction equilibrium constant
= *2*1 = 4.87 .Va>’b
- Suppose the feed to the reactor consists of mao, «bo- hcu- «do, and »» gram-moles of A, B, C, D. and an inert gas, I. respectively. Let £ be the extent of reaction. Write expressions for the gram-moles of each reactive species in the final product, «a(?)- «b(?)- «e(£). and uo(£). Then use these expressions and the given equilibrium constant to derive an equation for £c, the equilibrium extent of reaction, in terms of «ao- • • .,««). (see Example 4.6-2.)
- If the feed to the reactor contains equimolar quantities of methanol and acetic acid and no other species, calculate the equilibrium fractional conversion.
