Question

The process of fermentation involves chemical reactions that convert solid glucose (C6H12O6) into aqueous ethanol and carbon dioxide gas. Suggest how the speed of reaction alters as the temperature changes from 60C to 30C.

Answer 1

Explanation:

The glucose molecules changes as following:

C6H12O6 —> C2H5OH + CO2

There are 12 atoms of H on the left side and 6 atoms of the right side. It can be balance by putting 2 in front of C2H5OH as shown below:

C6H12O6 —> 2C2H5OH + CO2

There are 6 atoms of C on the left side and 5 atoms on the right side. It can be balance by putting 2 in front of CO2 as shown below:

C6H12O6 —> 2C2H5OH + 2CO2
