Question

Use log-log, linear or semi-log graphing paper to find constants and to show that hypothesized relationship between parameters is reasonably well satisfied. A bactericide was added to a solution containing a population of 10' bacteria. At various times after this, the number of bacteria was measured and the following results were obtained. Establish an equation relating Y to T and determine all constants. How many bacteria will remain after 100 min? 3. Y(number10 of bacteria) 10% | 32-10° | 10° | 3.2.105 | 105 | 3.2.104 | 104 | 3.2.103 | 103
