The spontaneity of a reaction can be reversed by changing the conditions such as temperature, pressure, or concentration of reactants, or by adding a catalyst.
Yes it can
no. it is a chemical reaction. and so it cannot be reversed.
Reversibility
the redox reaction is reserved
The relationship between chemical equilibrium and the rates of forward and reversed reaction is they will both be equal. Meaning both of them will be just about the same.
can the reaction between alkali and acid be reversed
The Redox Reaction Is Reversed
No, the Haber process to make ammonia can be reversed
Physical, as it may be reversed through condensation.
cause chemical reactions cant be reversed
When an endothermic reaction is reversed, the process becomes exothermic. In an endothermic reaction, heat is absorbed from the surroundings, while reversing it means that the products now release heat as they convert back into reactants. This shift in energy flow changes the enthalpy change of the reaction from positive to negative, resulting in the release of energy. Consequently, the reverse reaction typically favors the formation of the reactants under suitable conditions.
