1 alanine + 1 oxalacetic acid {dble arrows} 1 pyruvic acid + asparic acid
what are 2 methods that would increase the yield of aspartic acid?

a method for making methanol is:
co + 2h2 {dble arrows} h3oh
what is the effect on the amount of methanol produced if the equilibrium mixture is compressed?
-
1. Removal of pyruvic acid (probably not that easy in practice, but this is just theory)
2. Addition of alanine and/or oxalacetic acid
Both of these will drive the reaction to the right.
The effect on the amount of methanol will be an increase. A compressed system will favour the side with less molecules.

wouldn't u be removing asparic acid so it produces more?
-
removing any product will drive the reaction towards the right, whether it be aspartic acid or pyruvic acid. driving the reaction to the right through forward reaction invariably results in the production of more aspartic acid. hope that helps
-
That is correct. The only reason why I excluded it is because the system will only partially recreate the lost aspartic acid, so the calculated yield would be lower (strictly speaking). Ultimately, you'd have more of the stuff though (assuming you didn't throw out the aspartic acid you originally removed).
