Run the widget below to generate a carbon species plot like the one found on page 431 of your text book to answer the following questions. The temp_C control allows you to change the temperature of the system in degrees Celsius. In [2]: from chm210 4 import CarbonDiagraml w = interactive (CarbonDiagraml, temp_C= (-50, 50)) display (w) temp_C 25 1.0 0.8 0.6 H2CO, HCO, - co3- 04 0.2 0.0 8 10 12 14 pH Q3a. Why does the plot change with temperature? ie. Think about what controls the fraction of each species present at equilibrium at a specific pH and what would cause that to be temperature dependent.
