Explanation:
Fractinal distillation is used in the production of gasoline, distilled water, xylene, alcohol, paraffin, kerosene, and many other liquids.
Answer:
455.4 mmHg
Explanation:
To solve this problem we can use <em>Gay Lussac's Law</em>, which describe the temperature and pressure of a gas, at constant volume and composition:
In this case:
We <u>input the data</u>:
- 621 mmHg * 231 K = P₂ * 315 K
And <u>solve for P₂</u>:
D. More collisions occur and the time required for the reaction decreases
This happens because according to collision theory, when energy (in this case, thermal energy) is applied to particles, they move/vibrate more quickly.
