Question

Which reaction produces a decrease in the entropy of the system? H2O (s) \to H2O (g) 4 NH3 (g) + 5 O2 (g) \to 4 NO (g) + 6 H2O (g) UF6 (s) \to U (s) + 3F2 (g) 2 HgO (s) \to 2 Hg (l) + O2 (g) Na (s) + 1/2 Cl2 (g) \to NaCl (s) 

          Which reaction produces a decrease in the entropy of the system?
H2O (s) \to H2O (g)
4 NH3 (g) + 5 O2 (g) \to 4 NO (g) + 6 H2O (g)
UF6 (s) \to U (s) + 3F2 (g)
2 HgO (s) \to 2 Hg (l) + O2 (g)
Na (s) + 1/2 Cl2 (g) \to NaCl (s)
Which reaction produces a decrease in the entropy of the system? H2O (s) →H2O (g) 4 NH3 (g) + 5 O2 (g) →4 NO (g) + 6 H2O (g) UF6 (s) →U (s) + 3F2 (g) 2 HgO (s) →2 Hg (l) + O2 (g) Na (s) + 1/2 Cl2 (g) →NaCl (s)

00:01 The option a, the reaction for ns3 gas plus 5 o2 gas gets converted into 4 no gas plus 6 h2 gas.
00:17 So for this equation total number of moles of the gas, total number of moles of the gas is 4 mole plus 6 mole which is equal to 10 moles.
00:29 N are more compared to reactant side which is this is for product side and then for the reactant side we have 4 mole plus 5 mole which is equal to 9 moles hence there is increase in enthalpy increase in enthalpy then we go for the b part of the equation option b so for that reaction as an a solid plus half cl to gas gets converted into an in a solid so during the reaction and ionic compound anasease is formed from its constituent elements and chlorine is the gas whereas sodium chloride formed is solid and there is hence there is decrease in enthalpy decrease in enthalpy then we go for the next part of the equation that is option number c we have for option number c we have the reaction as to hgio solid gets converted into 2 hg liquid plus o2 gas.
01:41 So during this reaction, the amount of moment in the particle increases...
