A physical change occur when the molecular structure of chemicals are not changed.
A chemical change occur when the molecular structure of chemicals is changed.
The difference is that chemical equilibrium is the equilibrium of products and reactants in a reaction while physical equilibrium is the equilibrium of the physical states of the same substance.
A chemical reaction will do the following; Change colour Create smoke A non chemical reaction (Physical Reaction) will do the following; Change State Be able to change back to the original materials

the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
energy released by the reaction or energy absorbed.
A physical change is reversible, a chemical change is not.
reactant + reactant = product
a physical change is reversible but a chemical change is irreversible
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
The difference between them is that in a chemical reaction, the chemical make up of the substance put into the experiment is changed or modified. In a physical change, only the physical attributes of the substance is changed, like size, shape, color, density, etc.
