Answer:
The correct option is: a. reversible reaction
Explanation:
In thermodynamics, Gibb's free energy is the quantitative measure of the <u>spontaneity or feasibility </u>of a chemical reaction, at fixed temperature and pressure.
It can also be described as the <u>maximum available work obtained from a closed system</u>. This maximum work can only be achieved in a reversible process, <u>at fixed pressure and temperature.</u>
<u>The Gibb's free energy (ΔG) is given by</u>: ΔG = ΔH - T.ΔS
Explanation:
option option B is the correct answer of given statement helium-4(He)=2
Answer:
The answer would be C, in both chemical and physical change, because everything is made up of matter. So if you have a chemical or physical change, that doesent change the total mass of your product ever.
