Determine the standard entropy change for the overall reaction.arrow_forwardUnder what conditions is the entropy of a substance equal to zero?arrow_forwardThe deciding factor on why HF is a weak acid and not a strong acid like the other hydrogen halides is entropy. What occurs when HF dissociates in water as compared to the other hydrogen halides?arrow_forward
- The element helium is thought to remain a liquid at absolute zero. Solid helium can be made only by exerting a pressure of about 26atm on a liquid sample. Is the entropy of liquid helium at absolute zero exactly zero? Why or why not?arrow_forwardThe third law of thermodynamics says that a perfect crystal at 0 K has zero entropy. The standard entropy of a substance, S can be determined by evaluating the energy required to carry out conversion from 0 K to standard conditions.
