IOM 2019, Експеримент — Задача 11. Exercise 2.5: Solubility-temperature dependence
The 4th International Olympiad of Metropolises — Carbon Dioxide Solubility in Water
Recommendations Regarding the Experiment
There are two long exercises in the proposed experiment. Exercise 1.5 and exercise 2.1 in total may take more than three hours to complete. Consider this fact when allocating time and responsibilities to the participants during the experiment.
Условие
Using the carbon dioxide solubility at room temperature as the reference point, calculate the carbon dioxide solubility at the water bath temperature from the data obtained. Write down basic formulas used for such calculation. Does the solubility of carbon dioxide increase or decrease with increasing temperature?
Отговори
0.5
Solubility at the water bath temperature (50.8 °C); the solubility falls as the temperature rises ("Fall" underlined).
Решение
Exercise 2.5
Solubility of gas at the water bath temperature: 0.5
Does the solubility rise or fall as the temperature rises? (Underline the correct answer)
| Rise | Fall |
|---|
