Question

Why are state functions important in chemistry?

• A. They appear a lot in thermochemistry and thermodynamics
• B. Many equations include properties that are state functions
• C. We only need to know the final and initial states
• D. They simplify our calculations
• E. All answers are correct

Answer 1

Answer: (C)

We only need to know the final and initial states

State functions help us simplify our calculations and see the change in value between the final and starting position, also known as a state change. Mass, pressure, density, energy, temperature, volume, enthalpy, entropy, Gibbs free energy and chemical composition are all examples of state functions in thermochemistry

In simple words, the state functions are important in chemistry as we only need to know the final and initial states.

Hence, the correct option is $C$
