The fungus Aspergillus produces citric acid (C6H8O7) from glucose (C6H1206) in aerobic process. In a large batch reactor the following measurements are made at different times. The volume V decreases due to water evaporation. Calculate qp in the time range of the measurements, with the proper unit.
