To find:
The percent decrease in the total pressure of a sealed reaction vessel during the reaction between
Answer to Problem 10.107QA
Solution:
There will be
Explanation of Solution
1) Concept:
According to
i.e.
Decrease in percent can be calculated by the following formula:
2) Formula:
i)
ii)
3) Given:
i) Initial Partial pressure of
ii) Initial Partial pressure of
4) Calculation:
Total pressure before reaction is
The balanced equation is
Half of the hydrogen gas reacted, therefore partial pressure of
Since the mole ratio of
Partial pressure of
The mole ratio of
Total pressure after the reaction is
Percent decrease in pressure after the reaction is
Therefore, there will be
Conclusion:
The partial pressure of each gas after the reaction is calculated using the stoichiometry of the reaction at the constant volume.
