A state function depends upon the _.
Correct answer: D. Both initial and final conditions of the system
- A. Initial condition of the system
- B. Final condition of the system
- C. Path of the system
- D. Both initial and final conditions of the system
Explanation
STATE FUNCTION:A state function is the property of the system that depends on the initial and final states and is independent of the path adopted to bring about the change. For Example, if we heat a sample of water from 0o C to 25o C, the temperature change is equal to the difference between the final and initial temperatures. The way the temperature change is brought about has no effect on the result. ΔT = Tfinal - Tinitial ΔT = 25o C - 0o C ΔT = 25o C OPTION A: A state function does not depend on the initial condition of the system only. OPTION B: A state function does not depend on the final condition of the system only. OPTION C: As explained above, the state function is independent of the path of the system. OPTION D: It depends on both the initial and final conditions. Hence D is the correct option.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
