A is the answer to this question. Thank you.
Measure reactants precisely.
Stir to help the reaction take place.
Wait patiently until the reaction completes.
Make sure to recover as much copper as possible.
Explanation:
Anything that increases the rate of this reaction will improve the yield of copper production.
The rate of reaction is usually a factor of how the concentration of reactants and products changes with time.
Some of the factors that affects the rate of a reaction are:
- Nature of reactants
- concentration or pressure if gases
- temperature
- presence of catalysts
- degree of mixing
In this reaction:
- to ensure we have the maximum amount of copper produced, measure out the exact/accurate amount of reactants stated
- make sure you stir the reactants to ensure they mix and combine.
- ensure you are not too much in haste. Wait for the reaction to go into completion.
- recover as much copper as possible
