Mention the factors that affect the rate of a chemical reaction.
The factors that affect the rate of a reaction are as follows.
(i) Concentration of reactants (pressure in case of gases)
(ii) Temperature
(iii) Presence of a catalyst
Explain the different factors influencing the rate of chemical reaction.
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.
