Please can somone answer my doubtful doubt!
For varying concentrations of acid in reactions and looking at rates, why sometimes when they sketch a graph, increasing the concentration of acid still has same amount of product (gas) produced, but other times, when double concentration, the gas volume doubles?
Majorly confused. How about with surface area and temperature, do they have an effect on the final amount of gas produced?
OK, I get a part of your ques. Is this what you are looking for?..
Zn + 2HCl ---> ZnCl2 + H2
Conc. for acid doubled, but same amount of Zn used reaction faster but results in same volume of H2 gas.
Doubling the amount of both reactants results in doubling of product (gas).
Surface area and Temperature doesn't have anything to do with the yield, they only influenced the rate of reaction. Posting a q. as an example would do good as I still cannot properly get your question. Usually in the ques it is mentioned right, when the conc of reactants in increased/decreased.
