Question

Select the correct options among the following concerning "The rate of a chemical reaction increases" :

• A. if the temperature is increased
• B. if the surface area of the reactant is increased
• C. if the concentration of the reactants is increased
• D. none of the above

Answer 1

Answer: (A), (B), (C)

The correct options are
A if the temperature is increased
B if the surface area of the reactant is increased
C if the concentration of the reactants is increased

Rate of chemical reaction depends upon temperature surface area of reactant and concentration of reaction.
When temperature surface area of reactant and concentration of reaction are increased, the rate of the reaction increases.
