The factors which affect the rate of the reaction are
The correct options are
A The concentration of reactants.
B The nature of the reactants.
C The surface area of the solids.
D The pressure of the gases.
The rate of the reaction determines the speed by which the chemical reaction proceeds. There are several factors which affect the rate of the reaction. These factors are:
(i) Concentration - Rate of reaction increases with increase in the concentration of the reactants
(ii) Nature of the reactant - The state, reactivity or the solution kind of reactants also affects the rate of the reaction.
(iii) Pressure - Increasing the pressure on a reaction involving reacting gases increases the rate of reaction. Changing the pressure on a reaction that involves only solids or liquids has no effect on the rate.
(iv) Surface area of solids - Rate of reaction increases with an increase in the exposed surface area.
(v) Temperature - Rate of reaction increases with an increase in the temperature of the reaction.
(vi) Catalyst - Rate of reaction increase with the use of the positive catalyst and decreases with the use of the negative catalyst.
