Solution

The correct options are
A. Nature of reactants
B. Temperature
C. Catalyst
The factors that influence the rate of chemical reactions are:

1) Nature of reactants: Powdered materials react more vigorously than solid materials. Moreover, reactivity increases if a material is in a liquid or gaseous state.

2) Temperature: Temperature increases the kinetic energy of molecules and thus the rate of reaction increases.

3) Catalyst: Catalysts do not take part in a reaction directly but increase the rate of a reaction.
(Note - Pressure will affect the rate of reaction if the reactants are in gaseous form.)

What factors influence the rate of chemical reaction? [3 MARKS]

Every chemical reaction has its own characteristic rate. It is affected by some important factors. The most important factors are 1 , temperature, 2 , 3 and surface area out of these factors rise/decrease in temperature, light quantity, rise in the concentration of reactants and surface area 4 the rate of reaction. Whereas as 5 alter the rate of reaction.
