Consider the liquid reaction 3A + 2B → 4C What could be the outlet composition if CAo = 100 mol/L in a batch reactor and the feed is an equimolar mixture of A and B? Assume that 5 mol of C was already present in the reactor initially.

Consider the liquid reaction 3A + 2B → 4C What could be the outlet composition if CAo = 100 mol/L in a batch reactor and the feed is an equimolar mixture of A and B? Assume that 5 mol of C was already present in the reactor initially. Correct Answer XA = 0.2, CB = 86.66, Cc = 31.66

Taking A as the key reactant and using material balance we get, CB = CAo*(1 – 2*XA/3) Cc = CAo*(5/100 + 4*XA/3)

Consider the gas reaction A + B → 3C Which of the following cannot be the outlet composition if FAo = 100 mol/s in a flow reactor with vo = 10 L/s and the feed is an equimolar mixture of A and B? Take the initial conditions as 1 atm, 273K and outlet condition as 2 atm, 300K.
In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.
