Respuesta :

Add a catalyst
- would increase rate of reaction;
Because adding catalyst would lower activation energies.

Decrease the concentration of a reactant
- would decrease rate of reaction; because there would be less molecule

Decrease the surface area of a solid reactant
 - decrease rate of reaction; less collisions because more particles would become isolated

Increase the temperature
- Would increase reaction; Because it would accelerate the movement of the particles and make them colliding faster

1. Add a catalyst

  • The addition of a catalyst would lead to an increase in the rate of reaction.
  • The catalyst brings about lower activation energies.

2. Decrease the concentration of a reactant

  • The reduction in the concentration of the reactant causes a reduced  rate of reaction
  • This is due to the fact that there is less molecule

3. Decrease the surface area of a solid reactant

  • Decreasing the surface area of the solid causes decrease rate of reaction
  • The collisions would be less because of particles isolation.

4. Increase the temperature

  • A temperature increase leads to increased reaction
  • It causes faster movement of particles and collisions.
