What's the answer and why?
3. Which statements below are TRUE for enthalpy and entropy? Enthalpy is the heat flow, q, under constant applied pressure. Standard conditions for entropy and enthalpy changes are 1 M concentration, 1 bar pressure and 298.15 K I II III The entropy change for a system is the amount of energy, at a IV he entropy change for a system is the amount of energy, at a given temperature, that is dispersed into motion of the molecules in the system. When the value of AH is negative, heat is released. When the value of AS is negative, entropy is increased. A) B) C) D) E) I, II and III I, III and IV II and IV III and IV Another combination is true.
