What is meant of '. ' in chemical reaction?
'.' shows the multiplication in chemical reaction.
What happens to the entropy in the reaction?
Entropy increases. In a reaction comprised of sub-reactions, some sub-reactions may show a decrease in entropy but the entire reaction will show an increase of entropy. As an example, the formation of sugar molecules by living organisms is a process that shows decrease in entropy at the expense of the loss of entropy by the sun.
