Question

Factors affecting the rate of chemical reaction experiment

Answer 1

Answer:

Factors that influence the reaction rates of chemical reactions include the concentration of reactants, temperature, the physical state of reactants and their dispersion, the solvent, and the presence of a catalyst.

Answer 2

       Factors affecting rate of a reaction

consider a reaction ,

       $\bold{\mathff{A+B \longrightarrow\:Products}}$

      The rate of a reaction is given by the expression,

 $\bold{\mathff{Rate = k[A]^{x}[B]^{y}}}$ where x and y may or may not equal to number of moles respectively.

Therefore, factors affecting rate,

• Concentration of reactants : The amount of reactants present in a reaction.

• Surface area of reactants : The area of reacting items

• Effect of temperature : Temperature can increase or decrease the rate according to the conditions of reaction ie, endothermic or exothermic

• Presence of catalyst : Catalyst increases the rate (usually) . If it decreases , it is known as inhibitor

• Presence of light : The light can act as a source of energy as well as a catalyst.
