How does molar entropy change with respect to states of matter?
How does the molar entropy of a substance change with increasing temperature? A) The molar entropy of a substance increases with increasing temperatures. B) The molar entropy of a substance decreases with increasing temperatures.
How does the standard entropy of a substance depend on its molar mass? 1. The standard entropy of a substance does not depend on its molar mass. 2. The larger the molar mass, the greater the entropy. 3. The larger the molar mass, the lower the entropy.
1. How does the entropy of the system change when (1 point each) a. A gas decomposes to products in solid states b. Fog decomposes to dry ice. C. A "new" gun used on the movie "eraser" vaporizes a human when they are hit d. A lake melts to go swimming
Sample problems 3: How does the entropy of the system change when the following occur: a) a so vaporizes; ce) a solid dissolves in water; d) a gas liquefies? as 2. The normal boiling point of methanol (CHsOH) is 64.7 Co, and its molar enthalpy of vaporization is Hap -71.8 kJ/mol.

a) Show that the molar entropy change, Asm, is given by ASm = Cy,m In + Rin" if one mole of an ideal gas is taken from T,,V, to T2, V, assuming that Cv.m is independent of temperature. b) Calculate the value of the molar entropy change, Asm, if one mole of N2(g) is expanded from 20.0 dm² at 273 K to 300 dm at 400 K. (Cp.m = 29.4 JK-Imol-?)
