Answer:
All chemical reactions occur at different rates.
Step-by-step 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".
