10. When ammonium chloride dissolves in water, the mixture becomes cool. For
this change, which is of a larger magnitude, TAS or AH?
11. For the reaction 2 H2(g) + O2(g) → 2 H₂O(1), which is more disordered, the
products or reactants?
12. What are the units for entropy?
13. On the basis of AG, decide if the reaction is spontaneous or non-spontaneous.
A. 2 H₂O2(aq) → O2(g) + 2 H₂O(1) AG = -211 kJ/mol
B. HCOOH() → CO2(g) + H2(g) AG = 119 kJ/mol

Expert Solution
Step 1

Thermodynamics is branch of chemistry in which we deal with amount of heat evolved or absorbed by the system. 

Entropy is measure of disorderness in the system. More the disorderness, more is the entropy.
