Answer:
With thermodynamics, one cannot determine the speed of a reaction.
Step-by-step explanation:
Chemical thermodynamics, a branch of chemistry that deals with study of interrelation of the heat and the work with the chemical reactions or with the physical changes of the state within confines of laws of thermodynamics.
Chemical thermodynamics' structure is derived from first two laws of chemical thermodynamics. From fundamental equations of Gibbs, a multitude of some equations which relates thermodynamic properties of thermodynamic system can be derived and can be used to calculate the reaction spontaneity, equilibrium constant, etc.
Thermodynamics predicts about the direction, feasibility and the extent of a chemical process, it does not tell anything about the rate at which a chemical process may proceed.
