Answer to Question #65810 in Physical Chemistry for umar

Question

Question 1 : The zeroth law of thermodynamics is based on the concept of
entropy
Conservation of energy
absolute zero temperature
thermodynamic equivalence

Question 2 : Which of these does not depict thermodynamics?
Rate of reaction
Performance of car engine
Melting of ice
Boiling water for coffee

Answer 1

Question 1: The zeroth law of thermodynamics – physical principle, stating that regardless of the initial state of an isolated system in the end, the thermodynamic equilibrium is established in it. And the zeroth law of thermodynamics – every equilibrium system is characterized by temperature - a physical quantity that describes the internal state of the system. Two systems that are in thermal equilibrium have the same temperature. So the correct answer: thermodynamic equivalence.

Question 2: The reaction rate - it kinetics. The reaction rate is not related to thermodynamics. So the сorrect answer: rate of reaction.

Answer: Question 1: thermodynamic equivalence;
Question 2: rate of reaction.
