Problem- Determine whether each of the following statements about the thermodynamic functions is true or false as they apply to chemical reactions.
1. Enthalpy and temperature are multiplied in the Gibbs free energy.
2. All spontaneous chemical reactions have no heat of reaction.
3. The heat of reaction at constant pressure is always equal to the work done by the reaction.
4. Positive enthalpy changes increase spontaneity.
5. The entropy change does not affect spontaneity.
I am in hurry anyone is there provide me the answer in quick phase
