Problem 3: A mixture of methanol and methyl acetate contains 25.0 wt% methanol. a) Using a single dimensional equation, determine the g-moles of methanol in 400.0 kg of the mixture. b) The flow rate of methyl acetate in the mixture is to be 200.0 lb-mole/h. What must the mixture flow rate be in lbm/h? Problem 4: How many of the following are found in 15.0 kmol of benzene (CH)? a) kg C6H6 c) mol C6H6 b) Ib-mole C6H d) mol (g-atom) Problem 5: The reaction A B is carried out in a laboratory reactor. According to a published article the concentration of A should vary with time as follows: CA = Cao exp(-kt) where Caois the initial concentration of A in the reactor and k is a constant. a) If CA and Cao are in lb-moles/ft and t is in minutes, what are the units of k? 1
