For which of the following reaction, change of enthalpy equals the change in internal energy ?

Identify the equation in which change in enthalpy is equal to change in internal energy

Why are we usually concerned with changes in enthalpy than changes in internal energy?

Give reason for the following: It is preferable to determine a change in enthalpy than change in internal energy.

Which of the following is the correct expression for the change in internal energy used for general case?

For chemical changes, why is the change in enthalpy more useful than the change in internal energy?

Consider the following statements: I. Change in enthalpy is always smaller than change in internal energy. II. The variation in enthalpy of a reaction with temperature is given by Kirchhoff's equation. III. The entropy change in reversible adiabatic process is equal to zero. Select the correct answer.

Which of the following has no change in the internal energy?

In which of the following process (es), there is no change in the internal energy of the system?

If the activation energy of both the forward and the backward reactions are equal, then change in internal energy is
