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
Answer: option (A)
Explanation: The convection current is generates in the mantle due to the heat radiated from the core of the earth. Due to this convection current, the lithospheric plates moves as the upper part of the mantle known as the asthenosphere, is the region which is viscous in nature and drives the plates to move. This is a repeating cycle that constantly forces the plates to move.
Thus the correct answer is option (A).
2. Oxygen because it has more mass
The number of electrons in an atom's outermost valence shell governs its bonding behaviors
