Question

Which are the factors affecting the rate of chemical reaction. Explain​

Answer 1

Explanation:

physical rate of reactant and surface area

temperature

presence of catalyst

concentration of reactant

Answer 2

Answer:

Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
