WebMay 4, 2015 · 3. NaCl dissolved in water has Law of 6. For a spontaneous process, the entropy of the universe is always greater than 0. This statement is often referred to as the Law of Thermodynamics. 7. The entropy for the reaction N2(g) + 3H2(g) = 2NH3(g) would be expected to be (positive, negative) 8. WebFeb 19, 2015 · The term "reversible process" does not mean that $\Delta G = 0$. Reversible process is an imaginary or idealized process which occurs in infinitesimally small steps, such that the system very close to equilibrium throughout the process. However, the infinite number of infinitesimally small steps would add up to an finite change.
