It is a reversible 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.
entropy of thermodynamic systems
yes because it is a naturally occurring process and all naturally occurring processes result in an increase in entropy.
It increases.
entropy of system for a reversible adiabatic process is equal to zero. entropy of system for a irreversible adiabatic process (like free expansion) can be achieved by the following formula: Delta S= n Cp ln(V2/V1) + n Cv ln (P2/P1)
reversible
The entropy does not remains constant if the system is not isolated.
The second law of thermodynamics, generally stated, is that the entropy of an isolated system always increases in any natural process where change occurs. In a system at equilibrium, of course, the entropy remains constant.
in general entropy will not decrease in a spontaneous process since spontaneous process are all irreversible ones. entropy can be reversed only through an reversible process by an ideal engine but it is impossible to create such an engine by violating second law of thermodynamics. hence entropy cannot be decreased practically
An irreversible process occurs whenever there is an increase in entropy. Entropy can be thought of as a measure of "wasted" energy, that is, energy that cannot be converted to useful work. Therefore any process which results in an increase in entropy wastes some portion of energy that cannot be recovered, and so the process is irreversible.
Negative entropy is a process or chemical reaction proceeds spontaneously in the forward direction.Positive entropy is a process proceeds spontaneously in reverse.
The reason that entropy increases is related to statistics. It is possible in theory that a process occurs in such a way that entropy decreases, but this is so unlikely that it will never happen in practice.

Increase in entropy.
entropy of thermodynamic systems
An isoentropic process is a chemical or thermodynamic process in which entropy does not change. An example a reversible adiabatic process is isoentropic.
Entropy for a reversible process is q/T 3600 J ÷ (273 + 24) = 12.12 J/K
