I think it depends on the type of reacting particles..but probably none increases
Measuring it before, after and during the reaction with a thermometer.
the mass increases during a chemical reaction. because if heated or cooled then it would put on more mass for the atom.
The temperature increases when energy is released during a chemical reaction.
NO
Increases reaction rate.
Raising the temperature makes chemical reactions faster.
The time the reaction takes increases.
It is a catalyst.
A catalyst undergoes no chemical change during a chemical reaction.
due to catalyst
Yes. A chemical reaction which absorbs heat during the reaction. The opposite to exothermic which releases heat during the reaction.
A catalyst doesn't undergo a chemical change during a chemical reaction.
