Change in entropy doesn't depend on:

Correct answer: D. Amount of the substance

  • A. Amount of heat added to the system
  • B. Amount of heat rejected from the system
  • C. Temperature of the substance
  • D. Amount of the substance

Explanation

Enthalpy change is a state function so it does not depend on the path taken by the reaction. it depends only on the difference of final and initial values of enthalpy change.

About System, Surroundings and State Functions

A system is the part of the universe under study, while everything outside it is the surroundings; the boundary separates them. State functions such as pressure, temperature, volume, internal energy and enthalpy depend only on the state, unlike heat and work, which depend on the path taken.
