Are heat and work path functions?
No, heat and work are not path functions. Heat and work are energy interactions between a system and its surroundings that depend on the process taken, not just the initial and final states. Path functions are properties whose values depend on the path followed to reach that state, such as change in temperature.
What value should the heat of the reaction have in a spontaneous reaction?
It can be + or - depending on the value of the entropy (∆S). Recall, that ∆G = ∆H - T∆S and for a spontaneous reaction, ∆G must be negative, so you can see how this will depend on the values and signs of both enthalpy and entropy.
Why is entropy irreversible?
It's not that entropy can't be reversed, it's that the entropy of the universe is always increasing. That means that while you can reduce the entropy of something, the entropy of another thing must go up even more so that in total, the entropy goes up.
What does the second law of thermodynamic say about entropy?
The entropy of the universe is increasing
Is entropy path dependent in thermodynamics?
No, entropy is not path dependent in thermodynamics.
What does Gibbs energy depend on?
it depends on the entropy and enathalpy of the reaction
Why entropy cannot find during irreversible process?
Entropy can be found in an irreversible process, just not directly. Since entropy is a state variable, you can invent a path connecting the initial and final states that does consist of reversible processes and then compute the total equilibrium change for that path.
Does the entropy of a system depend on number of moles?
If you take entropy as an extensive variable then the magnitude of the entropy does depend on the number of moles. If you take entropy as an intensive variable then its magnitude it dependent on the other variables you combined it with. However sense you always deal with entropy as a change in entropy the magnitude doesn't really matter.
Does entropy increase as mass increases?
No, entropy does not depend on mass. Entropy is a measure of disorder in a system and is influenced by factors such as temperature, volume, and energy distribution. It is not directly related to the mass of a system.
What does Gibbs's free energy depend on?
it depends on the entropy and enathalpy of the reaction

What quantities are considered state functions?
State functions are quantities in thermodynamics that depend only on the current state of a system, such as temperature, pressure, volume, internal energy, enthalpy, and entropy. These quantities are independent of the path taken to reach that state.
What would happen to the entropy in the reaction 203g 302g?
The increase in entropy will depend on the physical states of the reactants and products. If the reactants are solid and the products are gaseous, there will likely be an increase in entropy due to the increase in disorder. However, if both the reactants and products are in the same state, the change in entropy may be minimal.
What are some examples of state functions and how do they differ from other types of functions in thermodynamics?
State functions in thermodynamics include temperature, pressure, volume, internal energy, enthalpy, entropy, and Gibbs free energy. These functions are properties of a system that depend only on the current state of the system, not on how the system reached that state. This is in contrast to path functions, such as work and heat, which depend on the specific path taken to reach a particular state.
What is the scientific measure of disorder is called?
This is called entropy.
What is the entropy of HCOOH liquid?
The entropy of liquid formic acid (HCOOH) at a specific temperature can be calculated using the third law of thermodynamics and statistical mechanics. The entropy value will depend on the molecular structure, temperature, and specific conditions of the system.
