What are the four properties of chemical reactions that can affect the rate at which the reaction occurs.
gpt
Temperature, measurement of items, previous experiment residue, and other environmental factors, often noted as surface area and concentration of reactants for items rather 'measurement of items', and 'season' is generally 'pressure and also light', although prior results of it would only more accurately show 'catalysts left over' from previous experiments if the statement would otherwise likely refer left-over reagents.
