Answer:

A) 12 hours approximately

Duplication times vary depending on the microorganism in question.

Explanation:

Bacterial growth is the division of a bacterium into two daughter cells in a process called binary fission. Assuming that no case of mutation occurs, the resulting daughter cells will be genetically identical to the original cell. In this way the duplication of the bacterial population takes place.  The bacterial population experiences exponential growth.

Calorimetric studies show that the reaction is exothermic. 2NO2(g) N2O4(g) + 14.1 kcal. Based on this information, which one--if
FinnZ [79.3K]
In order for you to get the answer, please have in mind the following situation: To increase the molar concentration of N2O4(g), 2NO2(g) should also increase for equilibrium to occur. Now, this equation is exothermic. By <span>Le Chatelier's principle, equilibrium constant and reaction constants also come into play in terms of increasing or decreasing the temperature. After that I know you can find the answer. </span>
