- NOTE: If the reaction temperature is too low, little reaction occurs and only a small amount of product is produced (little formation of B) If the reaction temperature is too high, most of primary product B reacts to form a lower-value secondary product (too much of B reacts to form C). So there is a temperature between these limits that maximizes the profitability of this reactor Consider the following data for the cost and values of A, B, and C Cost and value: V=$0.15/mol (cost of A in feed) AF V=$0.10/mol (value of A in product) V=$0.50/mol (value of B in product) V=$0.20/mol (value of C in product) A B Use excel for the following calculation a.
