c- In process selection for production of a certain product. we should start looking for an alternate route if 1) PM0 3) Cost of raw materials is higher than value of products 4) Value of product is higher than cost of raw materials 5) Answer (1) and (3). d. In PFD, the yield of chemical reaction is calculated by dividing: 1) Reactant consumed in reaction / reactant fed to the reactor. 2) Reactant consumed in process /reactant fed to the process. 3) Moles of reactant to produce desired product / moles of limiting reactant reacted. e. Consider the demand function of quantity versus price [Q =C/Px] in which C and x are constants. Demand elasticity (E0) is: 1) C,x 2) x/C 3) C/x 4x 5) x2 Q0=1600125Pn and O2=440+165Pf. A particular product sold on the market has the following demand and supply functions: The equilibrium price for this product is: 1) 4 2) 6 (3) 8 4) 12 5) 14 g. The equilibrium quantity for the product in question f is: 1) 1000 2) 1100 3) 1200 4) 1300 5) 1400 h. The elasticity of demand at market equilibrium for question f is: 1) 1.15 2) 0.45 3)0.96 4) 1.25 5) 1.35
