Answer:
With thermodynamics, one cannot determine <u>the speed of a reaction</u>.
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.
<u>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.</u>

The answer is caves.. i think
Hey there!
This is not reversible.
We know that this is a chemical change because heat is released (it burned brightly) and it formed a new substance (white powder).
Chemical changes are usually not reversible.
Since this is a chemical change, then this is not reversible.
Hope this helps!
