We cover the ethanol fermentation and we have to determine how many alcohol has been produced. I measured the production of carbon dioxide for a time interval of 4 days, but unfortunately I started to measure the production not immediately, but two days after the fermentation started. Is there anyway to find out how many alcohol has been produced at all(including the two days I haven't measured). Or do you know a kinetic law that refers to my problem? Because we got told, that we should take notice of the complexity of enzyme reactions.
