Suppose the liquid phase consists of an equimolar mixture of compounds 1 and 2 at 350 K. Set up a system of equations that would allow you to calculate the pressure and composition of the vapor phase in equilibrium with this liquid at 350 K. You don’t need to solve the equations, but the number of equations and unknowns should be balanced such that they could be solved. You may assume the Margules parameters A12 and A21 are known even if you have no final answer to part A.
A pair of compounds identified as 1 and 2 have the following properties:
This pair of compounds forms an azeotrope at 350 K and P = 8.5 bar, with x1 = y1 = 0.31.
Answer the following statements true (T) or false (F)
1. The iso-revenue line reflects the rate at which the market is willing to substitute between two products as their prices change. 2. The production possibilities curve reflects the different products the business can produce given efficient use of its existing resources. 3. The slope of the production possibilities curve is called the marginal rate of technical substitution. 4. The slope of an isoquant is called the marginal rate of product transformation. 5. The shape of the long run average cost curve is typically U-shaped in practice.
