What is the internal energy of a system? What is the variable for internal energy?
1 answer:
Explanation:
Internal energy is the sum of all the energies inside or within a system because molecules of the system will have kinetic, potential, rotational, vibrational etc energies.
Internal energy arises because of random or disordered movement of particles within a system.
Therefore, internal energy of a system is the sum of kinetic and potential energy of all the particles present inside the system.
The variable for internal energy is "U". Also, change in internal energy is represented by .

Answer: 1)
Equilibrium constant is defined as the ratio of the product of concentration of products to the product of concentration of reactants each term raised to their stochiometric coefficients.
where [] = concentration in Molarity=
Thus
As the value of K is greater than 1, the reaction is product favored.
2)
3)
4) Reactions which do not continue to completion are called equilibrium reactions as the rate of forward reaction is equal to the rate of backward direction.
