Question

how can the rate of a reaction be increased

Answer 1

By adding a suitable reaction rate of reaction can be increased

Answer 2

Explanation:

Rate of a reaction depends on the concentration of reactants, temperature, dispersion of molecules, surface area of solid reactants, and presence of a catalyst.

• Concentration of reactants: More is the concentration of reactant then more is the number of particles present in the solvent. As a result, there will be more collisions and thus, the rate of reaction will also increase.

• Temperature: Higher is the temperature more will be the kinetic energy of molecules. This will cause greater number of collisions and hence rate of reaction will also increase.

• Surface area of solid reactants: More surface area means more number of particles and they will effectively collide with solvent molecules and thus, rate of reaction will increase.

• Presence of a catalyst: A catalyst helps in lowering the activation energy barrier so that molecules with lesser energy than activation energy can also participate into the chemical reaction and thus, there product formation will become faster. As a result, rate of reaction will increase.
