The is what needs to be overcome in a reaction so that it can proceed to the products.

The answer to this question would be: activation energy

Activation energy is the energy needed for the chemical reaction to occur. The energy can be written as KJ/mol or kkcal/mol. This activation energy can be lowered by adding a catalyst which in turn increases the reaction rate

Nonmetals usually react by gaining electrons

Theoretical temperature at which molecules stop moving and no more heat can be removed from the object. kelvin: absolute zero degrees. none of the above.
