WebFermentation rate and yeast concentration. After seeing that the rate of yeast fermentation does not depend on the concentration of sugar under the conditions of our experiments, we decided to see if it depends on the concentration of the yeast. We took two 20.0 g samples of glucose and added 7.0 g of yeast to one and 3.5 g to the other. WebThe reaction rate changes in direct proportion to the change in [O 3 ]. When [O 3] doubles from trial 1 to 2, the rate doubles; when [O 3] triples from trial 1 to 3, the rate increases also triples. Thus, the rate is directly proportional to [O 3 ], and n is equal to 1.The rate law is thus: rate = k[NO]1[O3]1 = k[NO][O3] Step 3.
