You are given pure samples of ammonia, nh3(g), and nitrogen trifluoride, nf3(g). what prediction would you make concerning their standard molar entropies at 298 k?

Respuesta :

The standard molar entropies at 298 K is

S°Ammonia < S°Nitrogen trifluoride.

How are standard entropies calculated?

  • The entropy of a substance can be calculated by measuring the amount of heat required to raise the temperature by a given amount in a reversible process. S° is the entropy of one mole of a substance in its standard state at one atmosphere of pressure.
  • The difference between the sum of the molar entropies of the products and the sum of the molar entropies of the reactants can be used to calculate the change in the standard molar entropy of a reaction.
  • The entropy or degree of randomness of one mole of a sample under standard state conditions is defined as standard molar entropy. The standard molar entropy unit is joules per mole Kelvin (J/molK).
