Skylar Dillon · Answer 1

The correct answer is "All chemical reactions occur at different rates".

Explanation:

The reaction speed is given by the amount of substance that is transformed into a given reaction per unit volume and time. Several factors influence the speed of a chemical reaction. One of them is the concentration of the reagents and the other the temperature, as well as the pressure.

Adyson · Answer 2

All chemical reactions occur at different rates.

Explanation:

The rate of a chemical reaction can the defined as the speed at which the chemical reaction occurs. It can also be defined as the speed at which the reactants disappear during a reaction or the speed at which products form.

All chemical reactions occur at different rates depending on some factors which include:

Concentration of reactants or pressure of reactants in case of gases Surface area of reactants (in case of solid) Temperature of reactions Nature of reactants Presence/absence of catalysts.

The correct answer is that "all chemical reactions occur at different rates".
