Answer:
See attached => LeChatelier's Principle
Explanation:
LeChatelier's Principle => If a stress is applied to a chemical reaction, the reaction chemistry will shift away from the applied stress and establish a new equilibrium having new concentration values different from the original concentration values.
There are three (3) principle stress factors that will cause disturb a chemical reaction and cause it to shift to establish a new equilibrium. These are ...
=> concentration effects,
=> temperature effects, and
=> pressure-volume effects.
The attached notes explain in general terms how to evaluate a chemical reaction under an applied stress factor and determine direction of shift to establish a new equilibrium stability. Compare and apply to the worksheet problems.
_______
Answers to worksheet (compare to attached notes)
1a. => increasing wt to product side => tilts right => shifts left
1b. => removing wt from reactant side => tilts right => shifts left,
1c. => increasing wt to product side => tilts right => shifts left
2a. => tilts left (excess wt from Hg), shifts right,
2b. => Increase pressure shifts toward lower molar gas volume side (right) Note: apply only to gas phase substances, Hg is in liquid phase.
3a. exothermic rxn => cooling => tilts left, rxn shifts right
3b. endothermic rxn => cooling => tilts right, rxn shifts left
3c. exothermic rxn => cooling => tilts left, rxn shifts right
_____________

Taking into account definition of percent yield, the percent yield for the reaction is 76.25%.
<h3>Percent yield</h3>The percent yield is the ratio of the actual return to the theoretical return expressed as a percentage.
The percent yield is calculated as the experimental yield divided by the theoretical yield multiplied by 100%:
where the theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.
<h3>Percent yield in this case</h3>In this case, you know:
- actual yield= 1.22 mol
- theorical yield= 1.60 mol
Replacing in the definition of percent yields:
Solving:
<u><em>percent yield= 76.25%</em></u>
Finally, the percent yield for the reaction is 76.25%.
