(a) Use data from Appendix D to calculate the standard entropy change at 25^∘ C for the reaction. N2 H4(ℓ)+3 O2(g) ⟶NO2(g)+2 H2 O(ℓ) (b) Suppose the hydrazine (N2 H4) is in the gaseous, rather than liquid, state. Will the entropy change for its reaction with oxygen be higher or lower than that calculated in part (a)? (Hint: Entropies of reaction can be added when chemical equations are added, in the same way that Hess's law allows enthalpies to be added.) | Numerade

(a) Use data from Appendix D to calculate the standard entropy change at 25^∘ C for the reaction CH3 COOH( g)+NH3( g) ⟶ CH3 NH2( g)+CO2( g)+H2( g) (b) Suppose that 1.00 mol each of solid acetamide, CH3 CONH2(s), and water, H2 O(ℓ), react to give the same products. Will the standard entropy change be larger or smaller than that calculated for the reaction in part (a)? | Numerade

SOLVED:Without doing a calculation, predict whether the entropy change is positive or negative when each reaction occurs in the direction it is written. (a) CH3 OH(ℓ) ⟶CO(g) 2 H2( g) (b) Br2(ℓ) H2( g) ⟶2 HBr(g) (c) C3 H8( g) ⟶C2 H4( g) CH4( g) (d) Ag^ (aq) I^-(aq) ⟶AgI(s)
