[See Below]
Explanation:
✦ Physical Changes:
✧ Is when the form changes, but not the chemicals in that form.
✧ An example of this would be chopping wood. It's still wood but it's a different size now. It's easier to burn it since it's smaller.
✦ Chemical Changes:
✧ Is when the chemicals inside that form change to something else entirely
✧ An example would be an egg, when you cook the egg it can turn into being scrambled or fried. But you can't eat the raw egg until the chemicals change.

Answer:
The reaction will be non spontaneous at these concentrations.
Explanation:
Expression for an equilibrium constant :
Solubility product of the reaction:
Reaction between Gibb's free energy and equilibrium constant if given as:
Gibb's free energy when concentration and
Reaction quotient of an equilibrium = Q
- For reaction to spontaneous reaction:
.
- For reaction to non spontaneous reaction:
.
Since ,the value of Gibbs free energy is greater than zero which means reaction will be non spontaneous at these concentrations
