The environment would have most likely been covered in deep water such as in a lake or swamp. One with clay particle and other fine particle sediments.
Explanation:
A reversible reaction is a reaction which results in the formation of products which gives back reactants. Therefore, it is said that a reversible reaction occurs in both forward and backward direction.
Thus, it can be concluded that a reversible reaction is a reaction that takes place in the both directions . If the reaction were to equilibrium, the rate of the forward reaction would equal that of the reverse reaction.equilibrium.
