Question

Of the following, the entropy of is the largest. A) BF_3 (g) B) B_2H_6 (g) C) B_2O_3(s) D) B_2F_4 (g) E) BC1_3 (1) 2) Which of the following statements is false? A) The total entropy of the universe increases in any spontaneous process. B) The change in entropy in a system depends on the initial and final states of the system and the path taken from one state to the other. C) Any irreversible process results in an overall increase in entropy. D) Entropy increases with the number of microstates of the system. 3) DeltaS is positive for the reaction. A) Pb(NO_3)_2 (aq) + 2KI(aq) rightarrow PbI_2 (s) + 2KNO_3 (aq) B) 2H_2O (g) rightarrow 2H_2 (g) + O_2 (g) C) Ag^+ (aq) + CI^- (aq) rightarrow AgCI (s) D) NO (g) + O_2 (g) rightarrow NO_2 (g) E) H_2O (g) rightarrow H_2O (s) 4) The normal boiling point of C_2C1_3F_3 is 47.6 degreeC and its molar enthalpy of vaporization is 27.49 kj/mol What is the change in entropy in the system in J/K when 28.6 grams of C_2C1_3F_3 vaporizes to a gas at the normal boiling point? A) 13.1 B) -13.1 C) 4.19 D) 27.5 E) -4.19

Explanation / Answer

1)
gas will have largest entropy
In case of more than 1 gases, gas with smaller mass will have larger entropy
Answer: A

2)
Answer: B
entropy is state function and doesn't depend on path taken

3)
Answer: B
since product has more gases than reactants
