Why are state functions important in chemistry?
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 $$C$$
The internal energy change when a system goes from state $$A$$ to $$B$$ is $$40 \ kJmole^{-1}$$. If the system goes from $$A$$ to $$B$$ by a reversible path and returns to state $$A$$ by an irreversible path, what would be the net change in internal energy?
Which one of the following statements is false?
Which of the following is not a state function?
Among the following, the state function(s) is(are):
Choose the correct answer. A thermodynamic state function is a quantity :
Like $$U$$ and $$H, S$$ is also a state function.
Which one of the following quantity is dependent on path?
Entropy change of a system is determined by the initial and final states only, irrespective of how the system has changed its states. If true enter 1 else 0
Which of the following is a state function and also an extensive property?
