Of the two compounds which compound will have higher standard molar entropy at 25 oC: H H ہم H=C C CH3 H2C: H م H H H (1)
Please explain which. Thanks. of the two compounds which compound will have higher standard molar entropy at 25 °C h H CH H H <I TIN
Calculate the standard entropy change for the reaction at 25°C. Standard molar entropy values can be found in this table. HCl(g) + NaOH(s) + NaCl(s) + H,O(1) AS mol)
For each pair of substances, choose the one that you expect to have the higher standard molar entropy (s ) at 25 degrees celsius 1) NaNO3(s) or Na NO3 (aq) 2) CH4(g) or CH3CH3(g) 3) Br2(l) or Br2(g) 4) Br2(g) or F2(g) 5) PCl3(g) or PCl5(g) 6) CH3CH2CH2CH3(g) or SO2(g)
For each pair of substances, circle the one with the higher standard molar entropy (S°) at 25 °C. Explain a. I(s) or I(g) Reason:________________________________________________________ b. C(s, diamond) or C(s, graphite) Reason:_______________________________________
Without referring to a data table, arrange the compounds from highest to lowest standard molar entropy, Sº. Highest S Lowest S Answer Bank N,(g) C,H,() H,()

Which of the substances below will have the greatest standard molar entropy? C4H10(g) C4H10(l) Xe(g) Which of the substances below will have the greatest standard molar entropy? C4H10(g) C4H10(l) Xe(g) C4H10(g), because it is a gas and as such has translational, rotational, and vibrational modes, allowing for greater energy dispersal C4H10(l), because it is a liquid, so the molecules are in close contact with one another, making the dispersal of energy more efficient Xe, because it has the greatest molar...
