lowering the amount of reactants


adding a catalyst


having more surface area


raising the temperature

Answer 1

lowering the amount of reactants

Step-by-step explanation:

i got 100% on a quiz this is right

Answer 2

Lowering the amount of reactants

Step-by-step explanation:

• The rate of reaction refers to the speed at which products are formed from the reactants.
• The rate of reaction depends on several factors which include the concentration of reactants, temperature, presence of a catalyst, and surface area of reactants among others.
• The rate of reaction increases with an increase in the concentration of reactants as there will be more collision between particles of reactants resulting in the formation of more products.
• Catalysts speed up chemical reactions without being consumed by the reaction.
• An increase in temperature increases the rate of endothermic reaction but decreases the rate of an exothermic reaction.
• An increase in the surface area of reactants increases the rate of reaction due to the increased number of collisions between particles of reactants.
