Hello, I have to give a chemistry presentation soon on the topic of lead-acid batteries. This naturally includes the reactions that occur during charging and discharging. A few questions have piled up during the discharging process, and I don't know how to help with them. I'll just explain to you how I understood it and…
In a company laboratory, for a quantitative determination, 100 cm3 of a saline solution to be tested (starting solution) is filled with distilled water to 1000 cm3, 10 cm3 of the diluted solution is taken, this amount is poured into a beaker, and silver nitrate solution is added. Calculate the mass fraction of sodium chloride…
Hello I always sweat a little, and my clothes start to smell very quickly. How can I avoid having to wash my clothes so often?
I think it has an amino group with an electronegativity difference of 0.8, and an OH group in the carboxyl group, which is also polar? Furthermore, the main chain is monoatomic.
I'm currently drinking cola with wine and ice cubes made from chlorinated tap water from Spain. My question is, could chloroform theoretically be formed in this mixture?

You are perfectly right, but there is a conflict between two rules:
Displacement of equilibrium (Lavoisier) against RGT rule.
A lower temperature would increase the yield, but as a result the speed becomes unprofitably low. We must therefore take a compromise.

In equilibrium reactions, only one reaction at high temperatures can be favored. In this case, the formation of NH3 is exothermic, i.e. lower temperatures are cheaper. This collides with the high activation energy, which is why a catalyst is necessary.
Generally, the equilibrium at T is low and p is highest at NH3, but at the same time it also takes forever until this equilibrium is actually established.
So if you have a lot of patience, you get the most product from the starting materials. However, if the time is considered to be constant, higher yields are also obtained at higher temperatures.
